I'm at work and they blocked the site... can you describe them to me so that I can answer your question?
EDIT: I don't think I would allow my kids (boys) to wear them... but my husband might let them wear a few.... he has a few of those types of shirts himself.
They probably have stretch marks... but all the make-up and stuff that they wear covers it all up. Have you ever seen celebs without make-up... some look terrible!
