Bra Fitting Full Figure Lingerie Intimate Wisdom

Making Sense Out of All the Bra Cup Sizes

Let me just state up front that if you wear a D cup size bra or smaller, you can ignore this posting – you won’t know what I’m talking about. IF, however, you’re bigger than a D, read on – I’m finally going to explain to you why you think different bra brands don’t fit you right when you buy what you think is your size.

Here’s the set up. Okay, you purchased a 36DDDD in Lunaire. You love it. It’s the perfect fit. You’ve found your size – hurray! Now, you see a bra by Freya that you want. You pull down the sizing options and… no 36DDDD. What’s going on? You find a Chantelle bra you like. Again, you look for your size; it’s not there. You see a Goddess bra. Again, no 36DDDD. “What is going on?” you say. “Is my size unique?” “Am I stuck with only one bra brand that fits me?”

Well, here’s what’s going on. Sizing for A to D cups is the same for all brands I’ve ever worked with. So, a C cup in one brand should be the same cup size in any other brand. And most of the time, this is absolutely true. However, once a brand goes beyond a D cup size, for some reason the naming of cup sizes became a free-for-all with every brand deciding for themselves what to call those cup sizes. Put another way, It’s not that your bra size is different in the various lingerie brands, but rather your size is simply called by another letter or group of letters.

In the scenario above, here are your proper bra sizes in the aforementioned brands:

Lunaire = 36DDDD

Freya = 36F

Chantelle = 36G

Goddess = 36F or 36FF

Here’s another frustration. You are told you’re a 36F. So now, armed with this fact, you march into a lingerie store and start trying on 36F bras. But many of them don’t fit. Why?

Again, 36F is not the same across all brands. If you are a perfect 36F in a Goddess bra, a 36F in Freya will be one cup size too big. In Elomi, their 36F bra will be 2 cup sizes too big. And, in some specific Goddess bra styles, your 36F could actually be too small.

After seeing this, I know you probably want to throw up your hands in disgust and frustration. Well, I don’t blame you. It took me a long time to wrap my arms around all the sizing names myself. But, having gone through this analysis, I discovered a simple trick to help you find your correct size in any lingerie brand. So, pay close attention, I’m about to make your bra sizing/fitting dilemma go away.

First, know that regardless of the cup size name, your band size number will always be the same. In our example of a 36DDDD, you can count on your band to be a 36 throughout all bra manufacturers. Now, for the cup size. Here’s my trick: don’t try and find a specific cup size when shopping. Instead, know how many cup sizes you are larger than a D cup. In our above Lunaire example, Lunaire sizes their cups as follows: D, DD, DDD, DDDD. As a DDDD wearer in Lunaire, you are 3 cup sizes larger than the standard D cup. So, when you want to find your size in another brand, simply find what out what cup size letter (or letters) they give to the 3rd size past D. Let’s look at a Chantelle bras. Chantelle cup sizes go D, E, F, G, H. The third cup size after D is G. So, you’re a 36G in Chantelle. Let’s look at Panache. They size D, DD, E, F, FF. You’re a 36F in Panache. Voila! You’ve got it!

Now, I can’t help it; I’m an Internet retailer. I would be remiss if I didn’t drop a pitch in for why you women above a D cup size should shop for bras on-line. So, here’s my argument. Online retailers have a greater selection of plus size and full figure bras to choose from, AND at HerRoom, I make sure the sizing is displayed sequentially from the smallest to largest on every style. This makes figuring out your size in any brand much easier. You can’t do this at a retail store, because the bras are not hanging in any specific size order. There’s my pitch.

After reading all this, if you’re still finding it all a little confusing, this chart is the ticket. Simply find your best fitting bra by size and brand. The vertical column will be your size in all other brands on the market today.
