Another way to achieve this is to bring the measuring tape around the back and up under the armpits across the top of the bust. For either of these measurements, if you get an odd number, make sure to round up to the nearest even number.

Subtract the bust measurement from the band measurement. Each inch will determine a cup size. For example, 1 inch is an A, 2 inch is a B, and so on.

Padding can help make your breasts look larger, while underwire can help lift. Knowing which of these things you want can help you choose. Go to the store and try on different kinds of push up bras to determine which kind works for your body type and for your comfort level.

Demi-cup bras and plunging neckline bras are great for low cut tops. Strapless, one strap, or razorback bras are good for evening gowns or outfits without sleeves or backs. [4] X Research source

Push up bras look good under v-neck shirts and sweaters. Make sure whatever push up bra you wear doesn’t bulge under your clothes. It should be flat and unnoticeable.

When you straighten back up, readjust the bra to make sure the breasts are sitting in the right position and that you don’t have any breast spillage over the top of the bra. If your bra is properly fitted, you will not have any part of your breast spilling out of the side of the bra.

The band across your back should lay horizontal. It should not be pulled up your back. If you had your bra properly fitted, you shouldn’t have any problems.

When wearing tight clothes, make sure your padded bra is seamless so that it looks smooth under your clothes. If your bra fits well, you should not have any unfortunate breasts or skin hanging over the bra and straps.
