Ref. No. 41/989

The answer to your question is as follows:
A Muslim should always keep on wearing the dress of pious persons. However, if one is wearing paint and shirt in which the contour of body parts is not exposed and the structure of hidden parts is not revealed then it may be allowable.
And Allah knows best
