Well, this is charming on every level. By "every level" I mean the 1.4 levels of meaning I am willing to grudgingly grant OPI because they are probably feeling extremely proud of their clever non-pun and I don't want to make them cry, and by "charming" I mean "incredibly off-putting and really messed up."
Hey, guess what, OPI? Nails are the one part of everyone's body that they pretty much feel OK about. Nobody's nails are too fat!
The nail polish industry has a special place in the world of make-up because nail polish is the only product that cannot be used to make you look like the more attractive person you're not. Nobody (I hope) is using nail polish to even out their blotchy skin tone, to make their tiny eyes look bigger, to make their cheekbones more prominent. Nail polish is something a woman (or man) does to please her-(or him)-self--what color do I want my nails to be, just because I like that color?
So, you know, thanks for ignoring that whole ability you had to make nail polish the only "beauty" industry segment free from the need to make women feel bad about themselves in order to sell more products. You didn't have to make this about disguising flaws; it could have been about celebrating choices.
Instead, you're a nail polish bottle calling itself fat.
