Depends on the styling and the age of the chick. An elderly hippy with a huge tie dye one between her boobs is acceptable. After a few drinks.
A young girl, with a nice body, and a very artfully done one, would be cool. Everyone else is getting stars and stuff now, which are actually p*rn star measurements for how many various acts she's performed, are getting boring.
Depends on where you are going to put it, what the colorings are, but I think it would be fine.
Ha, I don't like tattoos on anybody and I don't like peace signs because they remind me of that fad a while ago were everybody would wear peace signs on everything. This particular shirt was worn to death by my classmates back in middle school link so now anything with peace signs looks really tacky to me. But if you really like it then go for it! Afterall, this is my opinion on this and I'm sure someone else might find a peace sign super sexy or meaningful.
