I've always felt bad about my boob size, I've always used a 34B. But ever since I started my bc I've noticed that my bras weren't fitting right... I never really noticed an actual size difference tho. Yesterday I went to Victoria's Secret and got sized. The girl that helped me told me I should try a 32C because a B cup would be too small, so I tried it on & when she checked me she immediately made a face and said "this is still too small" and brought me a 32D and it fit me perfectly! I was actually really happy and immidiately felt better about myself.
