This add could negatively effect the teens self esteem because it has the words "Perfect" with "Every body". This along with the picture means to them that everybody needs to be 0 size, super model looking women. Someone who was a size 6 to 10, which is completely healthy and normal would question what they know to be okay, and possibly hate themselves for being that way. What they think the advertisement is saying is "You must look this way, and it is natural for EVERY BODY to look this way". But, it really is just saying that there are bra styles for every size.
