JOINER, Senior District Judge.Defendant James Perry appeals the sentence imposed following his conviction for bank robbery in violation of 18 U.S.C. § 2113(a), contending that the district court impermissibly enhanced his base offense level for the robbery offense by two points for obstruction of justice. Specifically, Perry contends that he has been punished twice for the same conduct, because he was also held in contempt and sentenced to a consecutive term of six months for the conduct on which the court relied in imposing the obstruction of justice enhancement. We conclude that the district court should not have imposed the obstruction of justice enhancement in light of the independent sentence imposed for contempt, and consequently remand for resentencing.
I.
This is Perry’s second appeal in this case, and the pertinent facts are set forth in this court’s prior opinion. United States v. Perry, 991 F.2d 304 (6th Cir.1993). Briefly, a branch of the Pikeville National Bank was robbed by a man described as having dark hair and a mustache and wearing a grey suit. A teller later identified Perry from a photo array. Perry subsequently appeared before the district court on a pretrial motion sporting a full beard. The court ordered Perry to shave in advance of trial, but Perry did not comply. As a result, the teller was unable to identify Perry at trial, although there was other evidence linking Perry to the crime.
While the jury was deliberating, the court conducted a contempt hearing, and concluded that Perry had committed an act of contempt by refusing to comply with its order to appear clean shaven at trial, and concluded further that this act had obstructed the court by necessitating further proofs at the trial. The court sentenced Perry to a six-month term for contempt, to be served consecutively to any term imposed for bank robbery. The jury returned shortly thereafter with a guilty verdict on the robbery charge.
The district court enhanced Perry’s robbery offense level by two levels for obstruction of justice, relying on three independent grounds, one of which was Perry’s failure to appear clean shaven at trial. As enhanced, Perry’s total offense level was 27, with a resulting sentencing range of 78 to 97 months. The court imposed a 97-month sentence. Without the obstruction of justice enhancement, Perry’s offense level would have been 25, with a resulting range of 63 to 78 months. Thus, Perry’s refusal to shave resulted in an additional 25 months in prison, the six-month contempt term, plus the 19-month differential between the máximums of the two potentially applicable ranges.
On appeal, this court found that two of the three grounds upon which the district court relied to impose the obstruction of justice enhancement were not valid.
As to the first ground, the refusal to appear at trial clean shaven may warrant the enhancement. Perry attempted to disguise himself behind a full-grown beard and succeeded in part — the bank teller was unable to positively, identify him in court. Although this had minimal evidentiary impact on the case because other evidence linked Perry to the crime, it is nonetheless an attempt to obstruct the prosecution of the case.
Perry, 991 F.2d at 312. This court vacated Perry’s sentence, instructing the district court to consider whether the failure to ap*710pear clean shaven at trial alone was sufficient to justify the enhancement.
On remand, Perry challenged the obstruction of justice enhancement because the failure to appear clean shaven had “minimal evidentiary impact” and because the jury instructions cured any problem that resulted. As to these objections, abandoned on this appeal, the district court properly noted that the enhancement can be imposed for an attempt to obstruct justice. Perry also challenged the enhancement on the ground that the court had held him in contempt for the very same conduct. The court responded, stating: “And regardless of whether he obeyed my Order to shave or not, which is another matter, the fact is, that he grew the beard in an attempt to hinder the prosecution, to make it difficult to identify him.” The court concluded that Perry’s failure to appear clean shaven was sufficient in itself to impose the obstruction of justice enhancement, a finding which Perry does not challenge in this court.
II.
On appeal, Perry reiterates the argument he advanced in the district court that his failure to shave should not have been counted twice in imposing punishment, and, consequently, that his base offense level improperly was enhanced by two levels for obstruction of justice.
At the outset, we address the government’s argument that Perry was not sentenced twice for the same conduct, but was punished through the obstruction of justice enhancement for the growing of his beard, and separately through the contempt conviction, for the distinct act of refusing to shave his beard. This argument overlooks the reality that the court’s order to shave was designed to address the risk that in-court identification would be hampered by Perry’s beard. Likewise, the obstruction of justice enhancement was imposed based on a finding that Perry intended to impede the administration of justice by appearing at trial with a beard. Whether Perry grew a beard in advance of trial would have been wholly irrelevant if he had shaved it prior to trial, pursuant to court order or not. To draw a distinction between the growing of the beard and the refusal to shave as justifying separate and cumulative punishments overlooks the fact that it was simply Perry’s appearance at trial wearing a beard that resulted in the punishment.
Moreover, despite advancing this argument, the government commendably concedes that there is an issue as to whether Perry’s sentences for his contempt and bank robbery convictions should have been calculated pursuant to U.S.S.G. § 3C1.1, a point on which we agree, and conclude necessitates resentencing. Guideline § 3C1.1 provides that “[i]f the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the investigation, prosecution, or sentencing of the instant offense, increase the offense level by 2 levels.” Comment 6 to this guideline states:
Where the defendant is convicted for an offense covered by § 2J1.1 (Contempt), § 2J1.2 (Obstruction of Justice), § 2J1.3 (Perjury or Subornation of Perjury), § 2J1.5 (Failure to Appear by Material Witness), § 2J1.6 (Failure to Appear by Defendant), § 2J1.8 (Bribery of Witness), or § 2J1.9 (Payment to Witness), this adjustment is not to be applied to the offense level for that offense except where a significant further obstruction occurred during the investigation or prosecution of the obstruction offense itself {e.g., where the defendant threatened a witness during the course of the prosecution for the obstruction offense). Where the defendant is convicted both of the obstruction offense and the underlying offense, the count for the obstruction offense unll be grouped with the count for the underlying offense under subsection (c) of § SDl.2 (Groups of Closely-Related Counts). The offense level for that group of closely-related counts will be the offense level for the underlying offense increased by the 2-level adjustment specified by this section, or the offense level for the obstruction offense, whichever is greater.
U.S.S.G. § 3C1.1, comment, (n.6) (emphasis added). “[Cjommentary in the Guidelines Manual that interprets or explains a guide*711line is authoritative unless it violates the Constitution or a federal statute, or is inconsistent with, or a plainly erroneous reading of, the guideline.” Stinson v. United States, — U.S. -, -, 113 S.Ct. 1913, 1915, 123 L.Ed.2d 598 (1993).
It is the latter part of comment 6 which applies to the situation is this ease, where the defendant has been convicted of both an underlying offense and an obstruction offense. The underlying offense is the offense for which the sentence is sought to be enhanced for obstruction of justice. United States v. Winn, 948 F.2d 145, 161-62 (5th Cir.1991) (grouping required for underlying kidnapping offense and perjury offense), cert. denied, — U.S. -, 112 S.Ct. 1599, 118 L.Ed.2d 313 (1992); United States v. Williams, 935 F.2d 1531 (8th Cir.1991) (grouping of underlying fraud offense with jury tampering offense), cert. denied, — U.S. -, 112 S.Ct. 1189, 117 L.Ed.2d 431 (1992). In this case, the underlying offense is bank robbery, and the obstruction offense, which embraces the several described offenses in the first part of comment 6, is contempt.
Comment 6 instructs that the court first must group the underlying and obstruction offenses. Grouping comports not just with comment 6, but with the guideline referenced therein, U.S.S.G. § 3D1.2(c), which provides that counts should be grouped when one of the counts “embodies conduct that is treated as a specific offense characteristic in, or other adjustment to, the guideline applicable to another of the counts.”1 (Emphasis added.)
In grouping the counts, the court is to apply the highest offense level applicable to the offenses in the group. U.S.S.G. § 3D1.3(a). Pursuant to comment 6 to § 3C1.1, the court is then to enhance that offense level by two for obstruction of justice, and compare the resulting total offense level with the offense level for the obstruction offense. The greater of the two total offense levels is to be applied. This approach prevents double-counting of the same conduct in imposing sentence. United States v. Lincoln, 956 F.2d 1465, 1470-72 (8th Cir.), cert. denied, — U.S. -, 113 S.Ct. 259, 121 L.Ed.2d 190 (1992). Accord Winn, 948 F.2d at 161-62. Note 6 is thus consistent with the policy underlying the prohibition against double-counting conduct in the application of multiple guideline provisions. United States v. Romano, 970 F.2d 164, 166-67 (6th Cir.1992).
In this case, comment 6 required the district court to group the contempt and bank robbery counts and compute the offense level for those offenses, and then enhance that offense level by two points for obstruction of justice. Comment 6 then required the court to compare that offense level to the base offense level for criminal contempt alone. Guideline § 2J1.1, applicable to contempt, does not set forth a uniform base offense level because of significant differences in the circumstances in which contemptuous conduct occurs, but refers instead to the offense levels applicable to the crime of obstruction of justice, the highest of which is 15 when no personal injury or property damage is involved. U.S.S.G. § 2J1.2 (1991). Based on this, there is no question but that the enhanced offense level for the underlying offense, 27, was higher than that for contempt. Comment 6 thus required the court to sentence Perry based on this offense level.
The district court calculated Perry’s robbery offense level (as enhanced for obstruction of justice) at 27, and sentenced Perry to 97 months, the maximum term in the resulting range. The difficulty with this otherwise correct sentence is that it operated to imper-missibly double-count Perry’s refusal to appear clean shaven at trial, in light of the *712court’s previous imposition of the six-month contempt sentence. In an identical situation, the court in United States v. Williams, 922 F.2d 737, 739-40 (11th Cir.), cert. denied, — U.S. -, 112 S.Ct. 258, 116 L.Ed.2d 212 (1991), held that the defendant’s offense level for the underlying drug conviction could not be enhanced for obstruction of justice because he previously had been sentenced to a six-month term for contempt based on the very same conduct. We conclude, as did the court in Williams, that Perry’s contemptuous conduct may not serve as the basis for both an obstruction of justice enhancement and a contempt sentence, and that such a sentence constitutes impermissible double-counting. Having already sentenced Perry for contempt, it was not appropriate for the court to enhance the sentence for the underlying offense based on the same conduct involved in the contempt. Thus, under the particular facts of this case, we must direct the court on remand to resentence Perry without the obstruction of justice enhancement. However, we caution that in future eases, such a remedy will not be necessary if the court refrains from imposing a separate contempt sentence for the same conduct relied upon to justify an obstruction enhancement, rather than calculating the defendant’s sentence pursuant to the method prescribed in comment 6 to U.S.S.G. § 3C1.1.
Accordingly, we VACATE Perry’s sentence and REMAND this case for RESEN-TENCING consistent with this opinion.
. Comment 5 to § 3D 1.2 explains the operation of the guideline, stating:
[W]hen conduct that represents a separate count, e.g., bodily injury or obstruction of justice, is also a specific offense characteristic in or other adjustment to another count, the count represented by that conduct is to be grouped with the count to which it constitutes an aggravating factor.... [A] count such as obstruction of justice, which represents a Chapter Three adjustment and involves a different harm or societal interest than the underlying offense, is covered by subsection (c) even though it is not covered by subsection (a).
