Assalam walikum,

Recently, I accidently saw my male friend that he has worn women underwear inside his pants.

I have known him since college days.

He has been one of my muslim male friend is 100% straight person when I indirectly asked him he said that he feels very uncomfortable in those tight men innerwears, due to which lacks in concentration towards work and because of which he had to go to washroom every now and then to fix the inner things which causes some irriation and minor rashes near the abdomen.. so as a solutions to this, he buys new pair of innerwears of women brand from a shop and then wears new women underwear (as he feel comfortable in it and active at work). I want to know if this is fine or permissable as per Islam ?

I am asking this question as I can guide him to right path.

Waiting for your response.
