if you wear a hard-to-find bra size and victoria's secret shuts it's shiny glass doors on you, i highly recommend it.
i believe they carry band sizes 28-52, and cup sizes AA-K(?). It will be easier to find bras in the A-FF range, but i'm pretty sure i've seen bigger and smaller than that.
i've bought bras almost exclusively from here for the past several years. it's the only place i could find bras in a 30F. (fun fact--at my very very biggest, i was a G. it sucked.)
after i stopped nursing les bebes, i dropped a few cup sizes, but it's still hard to find bras. so i'm back to online bra shopping. yay.
(they also carry swimsuits, too. which is a blessing if you've ever felt like you were 'bust'ing out of your suit at the beach.)
so, why am i sharing this information with you? i don't know. just doing my part to send good vibes out into the universe, i guess.
and i remember the frustration of never ever ever being able to find a bra that fits, so...here's my gift to all the ladies out there who've ever cried in victoria's secret.
not that i've done that.
oh, wait. here's a picture.
now we're done.
