I so totally agree that it's very sad that adults try to push adult ideas on young girls' bra-wearing decisions. It's very sad -in fact it makes me angry and disgusted- that the multibillion dollar clothing industry sexualizes girls at a younger and younger age. A person would be naive indeed to 1) think that certain underwear, let's say push-up bras, do not mean certain things, don't have an explicitly adult, sexualizing purpose and 2) to ignore the influence the clothing industries, for example Victoria's Secret, have had on the marketing of girls' underwear, all girls clothing in general.
Huh. I was at Target the other day and my 6 year old daughter wanted an unlined bralette kind of sports bra thing "just like her counsellors have". (Outdoor camp counsellors/swim instructors). I was having a hard time understanding why they were even selling size small (girl's 6-8) bralettes. I know the quote reasons above did not cross my daughter's mind. I don't think I really though of it either. I just thought it was a completely unneccessary wardrobe item, not a completely inappropriate wardrobe item. Since she is a six 4-6 (XS), it wasn't a real issue now. I hope its not a issue next year! I am going to think of this differently now that we are embarking on the clothing outside the "toddler" sizes.
