Round down to the nearest even number and note your band size.

Bust Size

bust size

Now, take the measuring tape and wrap it around the highest part, which is the nipple area around the back of your shoulder, and round the measurement to the nearest whole number. Just keep it slightly loose thinking your breast would need some air underneath but not so loose.

Bra Size Guide: Find Your Perfect Bra Fit

To find yourself a perfect bra, you must consider going through a list of things on a bra. Apart from your bra size which is the measurement you will be wearing, there is a various factor that must be considered while buying a bra.

1. Band: A band might be the most important factor that you need to check before buying a bra. It supports your bust and helps them keep in the right shape and position. The band must perfectly fit your band line. It must not be too loose or too tight and firmly stand at their position. Basically, if you can fit a finger in between the band and your skin you are good to go.

2. Centre Gore: Center Gore is the main attraction in a bra. Either you want full coverage or want a plunge, the center gore is to be looked at closely. You have different bra types with different center gore. Just look for the one that covers your bust and rests them at their position holding them stable while wearing any bra on.

3. Cups: You have measured your cup size and you know the cup size you want. If there is any sort of hollowness in the cups then the bra is not for you. Or if they are pushing your bust then they might be smaller for you. Measuring your cup size is important for getting a perfect match for your bust.

4. Straps: Straps help you keep your breast in a stable position. If your straps are tight then it might leave you with marks on and probably resist blood flow around your chest and back. A loose strap might not keep your breast in a fixed position. Therefore straps must be considered very carefully to complete your quest for a perfect size bra for yourself.
