Proper Bra Sizing: What Every Woman Should Know

Most women do not wear the correct bra size. With monthly water retention cycles, dieting, and general aging, it also should not be assumed that the size you were two years ago is the same size you are today (or that a bra can be worn that long, for that matter). Even a change of 5 pounds can change your bra size. This guide will help you to properly measure your bust, so that you can find the size for you.

While most shops will have a salesperson to assist you in proper measurements, in order to buy sexy lingerie from a catalog, it is important to know your size.

How To Know If Your Current Bra Does Not Fit

The back rides up. This may mean that the cups are too small, or the band is too tight. The front of the band is too tight to get a finger under it. This means you need a larger band.

The bra cups should be entirely filled, or you may need a smaller cup. If, on the other hand, the cups are overflowing, you may need a larger cup or a different style of bra.

If the underwire digs in, you may need a larger cup size. (Or your bra could just be very old. In either case, it's time to replace it.) This could also be an indication that the side wings of the bra are not large enough.

Proper Measurements

First, you will need three measurements: under bust, upper bust, and full bust.
For under the bust, measure directly under your bust. With all measurements, hold the tape secure but not too tight. For the upper bust, measure above the bust and below the arms.

If the difference between the under and upper bust is less than two inches, the under bust is your band size (round up to nearest even number). If the difference is more than two inches, add 2-3" to the under bust measurement to get an even number and use this as your band size. For the full bust, measure around a fullest part of your breast. Make sure the tape is secure around the back.

Your cup size is determined by your full bust measurement - your upper bust measurement. If the difference is less than 1", you are a AA, 1" is an A, 2" is a B, 3" is a C, 4" is a D, 5" is a DD (or an E), etc.

Beyond Measurements

Of course, your measurements are just the beginning. There are other things to keep in mind when looking for a comfortable, yet sexy bra.

When trying on different bras, make sure that the area in between the two cups actually comes into contact with your chest. Do not make the straps support your breast alone! This will be very uncomfortable over long periods of time, the bra will wear out quickly, and the pressure on the straps can cause back problems.

If you are finding the band sizes to differ for a different brand, you may also need to change your cup size. Generally, as you decrease the band size, you will need to increase your cup size, while a larger band will call for a smaller cup.

Bra Styles

Different styles of bras have different fits. Beware the convertible bras: while they may sometimes work, it is rare that every possible style will work for your body.

Full Cup / Full Coverage - Designed for support, these bras cover the entire breast.

Half Cup / Demi Cup - These bras cover 75 percent of the breast. This is a sexy cut that increases cleavage, but make sure your breasts are not "cut-off" in the center. Your profile should still be smooth, and if it isn't, you need a larger cup size.

Underwire Bras - These bras give the most support.

Racerback Bras - These bras have a crossover pattern in the back. They can have a front or back clasp, or can simply pull over the head. This is a common style for a sports bra.

Halter-Top Bras - As the name imply, these bras have a strap that loops around the neck, rather than the usual shoulder straps. These bras can increase cleavage, and can be worn with both halter tops and tops with low center coverage.
Backless Bras - While some backless bras literally have only front coverage, generally this refers to bras with extremely low backs, so that many dresses with low backs can be worn without the bra showing.

Strapless Bras - These bras have no straps at all, only the band. Some of these can cover the stomach area as well, and some even cover the body like a leotard. These longer strapless bras tend to stay in place better.

Padded Bras / Push-Up Bras - These bras have extra padding in the cups in order to give the illusion of a larger breast and/or to increase the cleavage. The padding can be made of the same material as the bra, foam, or gel. Gel is becoming more popular because of its more natural look. In some bras, the padding is removable.
Décolleté - These bras are lower cut than a demi bra, allowing you to wear something even lower cut without revealing your bra.

Light-Support Bras - These bras have no underwire. While you may be tempted to wear one to an all-day event, if you are larger than an A cup, you may not be getting the support you need. A properly fitted bra will be comfortable whether or not it has underwire.

Sports Bra - These bras are designed to minimize bouncing during athletic activity. While some inexpensive varieties do this by squishing your breasts, it is better to find on that is sized by cup sizes (as opposed to small, medium, and large) and get fitted as you would with a regular bra. Over the long term, this will increase your comfort.

Nursing Bras - For the convenience of nursing mothers, these bras have a snap on each of the shoulder straps, so she can easily remove them to feed the baby without taking off the entire bra. Generally, nursing bras are full-coverage for the added support a new mother needs.
