Perfect Bra Fitting Tips and Tricks: Ladies (Tip 3)! Why To Choose Sister Size Bra?

Clothing shopping is usually a rather basic affair. As time goes on, the sizes grow larger, and that's all.

Bra sizes, on the other hand, aren't that straightforward. You must take into account characteristics such as your unique breast form, band size, and cup size, which rarely correspond to a single number and letter.

Sister sizes come into play here, and knowing them might help you locate the appropriate bra.

Why Knowing Your Bra Sister's Size Is Crucial?

You're not alone if you've battled to find a bra that fits your specific shape. It's no easy task, and it's even more difficult when you're unfamiliar with your sister's Bra measurements.

It's important to remember that it's your bra, not you, that's the problem.

Identifying your sister size is extremely useful if your cup or band aren't fitting properly.

Finding the right bra size might be difficult and irritating, but it is not impossible.

  • Sister sizes have varied body measurements (Band Size) but the same amount of breast tissue volume (Cup Size).

A 32D and 34C band bra, for example, both accommodate the same amount of breast tissue, but a 32D bra is made for a smaller rib cage and larger bust, whilst a 34C band bra is fashioned for a larger rib cage and smaller bust.

Kamison Pro Tip: Bra sizes are more akin to proportions. The band size affects the capacity of a cup size (or how much breast tissue it can hold). 

Sister sizing can make buying a bit easier, especially if you wear a size that's hard to come by.

How to Estimate the Sister Size Bra?

  1. If your band is too tight, go up a band size, but down a cup size.
  2. If your band is too big, the same rule applies: go down a band size while going up a cup size.

Kamison Experts guarantee it.

We made a quick sister size calculator for you to refer to because it just sounds more complicated than it is.

Your sister sizes are the ones listed in the same row as your current bra size (going across). So, if you're a 34C, your sister sizes are 30E, 32D, 36B, and 38A, respectively. Each row represents a family of sisters of various proportions.

Do You Know: an A cup might also be an E cup. Isn't it incredible?

Sister sizes are excellent because, despite being contradictory, they're essential for choosing a great-fitting bra.

You might think to yourself, "I'll just go up a band size and try a 36C," if you're wearing a 34C and the cups fit but the band is too tiny.

However, because a 36C's sister size is a 34D, scaling up in this manner will almost certainly result in cups that are too big.

The next size to attempt instead of a 34C is a 36B, which is the next sister size to a 34C. The cups will be the same size as before, but the band will be wider.

Here's a rundown of what you should do in a few different scenarios

  1. Your band is comfortable, but your cups aren't: Go up a cup size if the cups are too tiny. Go down a cup size if the cups feel too big. (For example, if the 32F seems too tiny in the cups, try a 32G.) Go down to a 32E if the 32F seems too big in the cups).
  1. Your cups are comfortable, but your band isn't: Both the band and the cup size need be adjusted. Remember that if you increase your band size, you must decrease your cup size, and vice versa. (For example, a 34C cup is equivalent to a 36B and 40E(DD) cup is equivalent to a 42D cup.)
  1. Your cup and band don't fit: If they're both too big, go down a band size; if they're both too small, go up a band size. Don't be concerned about adjusting your cup size; it will adapt naturally with your band! (For example, if a 32D is too tiny, go with a 34D.)

What Benefits Women Get After Wearing Sister Size Bra?

Individuals who might benefit from examining sister sizes include those who:

  • Wearing plus-size bands with little cups
  • Modest band sizes, such as a 26 or 28 (you may want to sister size up to a 30 or 32)
  • Due to a physical issue such as a third rib cage or fibromyalgia, you may find a larger band more comfortable.
  • Have a broad back like a swimmer

Kamison Pro Tip: To get a proper fit, you shouldn't adjust size more than two sizes in any direction.
