Indulge me for a moment here by assuming that you would actually buy a playsuit (or a pair of "jersey short-alls" as those crazy kids at American Apparel would have it) and that you would wear it. Now, I’m no expert on the whole dressing-like-a-toddler thing (actually, I kind of am, but… you know what I mean), but I’m going to take a wild guess and say that what you probably wouldn’t do is wear your playsuit with your nekkid boobies underneath it, your nipples cunningly concealed – but only just! – by the straps of the aforementioned playsuit, "glamour model" style. Would you? No, I didn’t think so.
Why, then, did American Apparel think that this would be a good way to advertise their short-alls? WHY? All I can say is: don’t try it at home, kids. Well, you know – you can try it at home – just don’t try it in public. The Fashion Police will know.
