Determining whether to opt for a D or DD cup size ultimately comes down to achieving the most comfortable and supportive fit. While the difference between the two sizes may seem subtle, it can significantly impact how well a bra supports and shapes your bust. Here are some guidelines to help you decide when to size up or down between D and DD cups.

2024年1月10日 · Understanding bra sizing can feel tricky to the uninitiated, especially when you reach DD letters from a D rather than going straight to E. How does it all work and which is right for you? Simply put, the difference between a D cup and a DD cup is that; a D cup is larger than an A, B or C cup and slightly smaller than an E cup.

How Big Is a DD Cup Size? A DD cup has a 5 inch difference between the bust and band measurements, which makes a double D an inch bigger than a D cup. If you have a DD cup bra size, your breasts can weigh up to 2.15 pounds (975g) each. Double D boobs are also the same as an E cup, depending on what bra brand you buy.

In this guide, I will discuss the DD cup and the perfect bras for this cup size. I will also explain the correct way to measure your bra size and show you how the same cup can appear dramatically different on different women.

2024年1月12日 · While the difference may seem subtle, D and DD bras vary distinctly in cup volume and fit. This guide will explain the nuances between D and DD sizes, how to determine which size you really need, and which bra styles work best for each cup size. For a fuller guide see this article by Uplifted Lingerie (D vs DD cup bras).

All of these bras are “DD” sizes for example – from 30DD to 38DD, each with a different band length and cup volume. To find out the best size for you if you already have a bra that is fitting relatively well, our fitting guide has step by step instructions of what to look for in a well-fitting bra, and which steps to take to improve it.

If your bra size is 34DD, your under bust size is 33-34 inches and your bust size is 39 inches. A DD cup-size bra means that your breasts stick out 5 inches from your torso. The sister sizes for a 34DD bra size are 32DDD, and 36D.

DD cup breasts, or “double D,” are a step up from the D cup in both volume and visual impact. For women opting for DD cup implants, achieving this size usually involves selecting implants around 350 to 450 cc, though again, this may vary based on existing tissue and desired results.
