Some clothes in
catalogs should by all rights
show a little nipple, but their catalog pictures have the nipples
airbrushed out for
PG-13-edness.
It's really freakish-looking to see a breast without a nipple; it's sort of just a big mass with no point, so to speak.
Take a look at a Playboy clothing catalog to see what I'm talking about. They have sheer bras and skin-tight tees with no nipples. Eerie.
