Do you think my boyfriend should reconsider wearing sweatpants they are revealing his small outline which isn't particularly flattering?

The other day, my best friend was over when my boyfriend was heading out in grey sweatpants, and she immediately reacted, saying Oh no, he actually goes out in public wearing those?

I told her he does and she went on to comment about how that in her opinion, he doesn’t quite have the right dick to pull off sweatpants which is why she thinks I should say something to him.. I reassured her that he’s not small he’s just a grower not a shower. She said she understood but still joked that his outline was definitely giving off small pp vibes. I get what she’s saying but I think there is no way or mentioning it without with insulting him.
