I initially hesitated posted about this, but I figured you already know how much I weigh, why would my bra size be any more intimate?
I went to a local bra specialty store to get fitted for a new one. A) My current bras are from last fall. They are supportive in name only. B) It's fun to get felt up by old ladies with tape measures.
I love this store because it's staffed by expert fitters and they will get you in the right size. You always hear that 85% of American women wear the wrong size bra, and left to our amateur devices, I believe it.
All I had to do was listen to the woman squawking a few fitting rooms down: This bra is too tight!
It's supposed to be tight, the saleswoman patiently explained. Again and again.
Anyway, I bought my old bras from this store, so I know they were the right size: 46DD.
After a fitting today, my new size: 40C. Woo!
