In a jury trial, defendant was convicted of simple and aggravated assault, and possession of an instrument of crime. After denial of post-verdict motions, defendant was sentenced to five to ten years imprisonment for aggravated assault, with a consecutive term of one to two years for possession of an instrument of crime. In this appeal from the judgment of sentence, defendant contends: (1) the court below abused its discretion in ruling that the chief Commonwealth witness was a competent witness; (2) trial counsel was ineffective in failing to request a specific chаrge that the effect of evidence of insanity of the chief Commonwealth witness on that witness’s credibility was properly a matter for the jury; (3) trial counsel was ineffective for failing to object to defendant’s appearаnce at his jury trial in prison garb; 1 and (4) the court below erred in refusing to *150 discharge defendant under Rule of Criminal Procedure 1100. Judge Guarino’s opinion adequatеly disposes of the first and fourth issues. For the reasons discussed below, we find the second issue without merit, but we also find that the allegations in defendant’s third issue would permit a finding of trial counsel ineffectiveness. Therefore we vacate the judgment of sentence, and remand for a hearing on the allegation that trial counsel was ineffective for fаiling to object to defendant’s appearance in prison garb at his jury trial. 2
There can be no finding of ineffectiveness of counsel unless the defendant demonstrates that the course not chosen by counsel would have provided a substantially greater probability of success.
Commonwealth v. Hubbard,
*151 Defendant’s other claim of ineffectiveness, trial counsel’s failure to object to defendant’s appearance before the jury in prison garb, is much more serious.
A defendаnt in prison garb gives the appearance of one whom the state regards as deserving to be so attired. It brands him as convicted in the state’s eyes. It insinuates that the defendant has been arrested not only on the charge bеing tried but also on other charges for which he is being incarcerated.
Commonwealth v. Keeler,
Defendant’s allegation concerning the prison garb does, howevеr, meet the requirement to “set forth an offer to prove at an appropriate hearing sufficient faсts upon which a reviewing court can conclude that trial counsel may have, in fact, been ineffective.”
Commonwealth v. Pettus,
Judgment of sentence vacated, and case remanded with instructions. Jurisdiction relinquished.
Notes
. At pоst-trial motions, defendant was represented by trial counsel, who raised the same substantive issues which are raised in tеrms of trial counsel’s ineffectiveness in issues (2) and (3) above. Judge Guarino properly found these issues waived because trial counsel failed to raise them at trial, raising them for the first time in post-verdict motions.
See
Pa.R.Crim.P. 1123(a). Defendant is reрresented by new counsel in this appeal, which is the first opportunity to raise issues (2) and (3) in terms of trial counsel’s ineffеctiveness; hence these issues are now properly before us. As an alternative to the ineffectivenеss claim with respect to issue (3), new counsel also claims that the prison garb issue could not be waived by mere failure to object, absent a knowing and intelligent express waiver by defendant himself. Clearly this alternative claim of non-waiver is incorrect.
Cf. Commonwealth v. Chew,
. In addition to the brief filed by defendant’s counsel in this appeal, defendant has filed some supplemental documents pro se, which we shall not consider because defendant is already represented by counsel.
