How to Measure Bra Size and Other Bra Shopping FAQs, Answered

glamour.com:

her personality, you'd think I'd know how to measure bra size, what cup size I wear, or, quite frankly, how to shop for the bras I need.

Alas, I do not. I sized out of Victoria's Secret before I turned 12. So while my peers had the formative experience of being (relatively) properly sized by an unfriendly sales associate with a tape measurer at the mall, I was told to shove my somewhere-around-F-or-G-cups into a Double D and hope for the best.

My approach to bra shopping hasn't evolved much since: it's still an ongoing “hoping for the best!" situation even two decades later.

Though honestly, it was working relatively fine until my breasts changed sizes again this year. (Apparently this happens every so often from either weight gain or loss or, I don't know, the wind blowing a bit too mightily.)Determined to grow as a person—and fit my hopefully now-stagnant breasts into a bra—I set out investigate, and ultimately write, how to properly once and for all.
