Why Your New Bra Size Can Come as a Shock

By Linda The Bra Lady on February 12th, 2013

Recently, Victoria Floethe from Look TV’s Sexy. Not Sexy. stopped into my Murray Hill shop for some “braducation” from one of my Bra Divas, Kim. Victoria is a very fashionable woman! And though she was wearing a very pretty pink and orange silk bralette, her bra did NOT fit. Turns out, Victoria was wearing the wrong bra size! Watch her reaction as my Bra Diva Kim teaches her some fitting basics, and introduces her to her new bra size. Let’s just say: She was floored! And guess what: so are a lot of women. Get the facts on learning your new bra size, what it means, and why it’s no big deal.


Learning your new bra size can be a big deal. Many women think they should be wearing a certain bra size, but after a quick measurement, some facts on how their bra should fit, and help from one of my Bra Divas, they realize they were pretty far off. In Victoria’s case, she was wearing bras in size 34B. After Kim examined her stretched out, barely supportive bra, and  breast shape, she picked the Simone Perele Andora bra for her in a 30C. Remember, every bra fits a bit differently, and this style fit Victoria perfectly in this new size! Victoria and her friend were flabbergasted – they could not believe that her petite bust could possibly be a C cup. As Victoria put it, she said she “got a promotion”.


Watch Victoria’s reaction as my Bra Diva, Kim, reveals her new bra size: 30C! 


Victoria and her friend just couldn’t believe her new bra size! And neither can a lot of my other customers. But here is the thing: A 30C (her new size), and a 34B (her old size), are not that far off. Here’s why:


The letter after your band size is your cup size. The cup size tells you the difference between the size of your breasts and the size of your ribcage. This brings me to a very important bra fitting tip: as the band size gets bigger, the cup gets bigger too. For example, a 36B bra has bigger cups than a 34B bra. If you go down to a smaller band size, your cup size has to go up if you want the same amount of space in the cup. So a 36B bra has the same size cup as a 34C bra. Or, in Victoria’s case, a 30C has the same cup size as a 32B, or 34A.



So it turns out, Victoria was really wearing her bras two back sizes too big, and one cup size too big. Although Victoria says it feels like a “promotion” to go from a 34B to a 30C … the cup size in her new bra is actually one cup size smaller than what she was typically buying. Funny, huh? But that’s the facts! I feel like the “promotion” that Victoria got was a bra that felt great, and gave her breasts a lifted and beautiful shape.


A lot of women have the same reaction as Victoria. They say “I could never be a ::enter cup size here::!” Many women often end up being a larger cup size than they are used to for a few reasons:

  1. Many women don’t know that a snug back band is the key to a great fit. Your bra’s band offers about 95% of the support! If it’s loose, the rest of your bra won’t fit, and your bra can’t do it’s job. And as we just learned, a smaller band means a larger cup size to get the same fit in the cup as before.

  2. Bra sizes have changed in the past 10 years. Many companies have made their bra bands a bit bigger than before. That means women need to shop for a smaller band for the right support, and subsequently, a seemingly larger cup size.

  3. Every bra fits differently. You may need a 32 band in one brand, or a 34 in another. To get the same space in the cup, you’ll have to change the cup size when you change the back size. That means you may wear a C in the 34, but a D in the 32. Totally normal!

  4. A small band means a small cup size. Many women who have a petite back size, like a 30 or 32, may have a larger cup size, like a D or DD. But in reality, their bust is not very large. Remember, a 30DD (for example) fits the same in the cup as a 32D, 34C, 36B or 38A. So that “big” cup size doesn’t seem so big once you compare it to the equal cup size in a larger band size. The letter just seems so big because the band is smaller.

With this in mind, don’t get too hung up on your cup size. Some women are shocked or upset when they find out they’re a AA or DD or G cup. In reality, the cup size is almost meaningless without the band size. Buy bras that make you look and feel great and don’t worry about the size on the tag. Nobody will know but you and me!
