Oh man, showing peeking nipples on the shirt could be the ugliest site ever. There is no way that this could be fashionably acceptable. NO and simply no! It is not sexy nor does it look hot. There are so many techniques that can help eliminate nip traces on the shirt. Most cotton shirts can be really flimsy at times and obviously this guy doesn’t know that his nips are popping.
In this given situation this is an eyesore for the fashion police. The immediate solution is to wear a vest or a jacket that can be a quick cover up. I would advise people who love wearing muscle shirt that these shirt can flaunt your bulging popping biceps and triceps, but never ever your nips. It is a total crime to show them. It is definitely poor taste and it can tell how much you don’t care about your look. The next time your man wears his muscle shirt give him the fashion advice to be conscious and look at the mirror before leaving the house. You just don’t want people staring at you in a very strange way, do you? So don’t let peeking nipples bring you down.
