I agree about not wasting your time/money on Victoria's Secret, especially not so early on. Call me ghetto but I did the old fashioned way..got some measuring tape when I started getting *actual* boobs, measured 30A (but it's impossible to find 30 band size soo I just stuck with 32s) went to Target and got some 32As. Those started getting too small, measured again, 32B (yayy!) went back to Target and got those.
I guess I've never understood the obsession with fancy underwear and such. The only time anyone actually sees it, it's generally coming right off, if we're being real. And sizing is a breeeze to do yourself. I say if you're early on, save your money for important stuff...doctors visits, hormones, clothes, makeup etc. Just my 2 cents.
