Look at how your current bra fits
If you’re currently wearing a bra that doesn’t fit well, it might be a bit difficult to determine your correct size. However, you can still try and ‘guestimate’ your bra size using it, as of your bra is visibly too small or too large in certain areas, it can give you a general idea of what size should fit your bust best. For example, if your cups are overflowing, you may need a larger cup size. Depending if band is riding up your back or its on the looser side, you may need a bigger or smaller band size.
While these methods can give you a rough estimate of your bra size, keep in mind that they may not be as accurate as simply measuring with a soft tape measure. If possible, it’s best to get measured by a bra expert at a lingerie store or simply find yourself measuring tape to ensure you’re getting the most accurate fit.
How should your bra sit?
The band
First up, the band itself. This should sit firm and straight. You should also be able to get two fingers under it but feel a little resistance. If it’s too loose, you need a smaller size. If you’re struggling to get your fingers in, then you should try the next size up. When buying a bra, try the band in its loosest setting, it a better reflection of how the fit is, as after prolonged use, bands stretch.
The straps
The straps are a key part of your bra. You’ll be forgiven for thinking that the tighter the straps the more support they provide, but they should actually sit comfortably on the shoulder without any pinching or sliding. Be sure to check they are equal on both sides.
The centre
Also known as the ‘bra bridge’, this is the little bit of fabric nestled snuggly between your boobs. It should sit flat to your body without any room underneath but also not digging into your skin. If you can see a gap, you need to go up in size.
The wires
If you’re testing out a bra with wiring, be sure to check it fits properly. These should follow the natural curve at the base of your breast. If they’re sitting on it or too far below, they won’t do their job and this is where a large amount of support comes from.
The cups
If all the other elements are adjusted correctly, your cups should be smooth and perfectly moulded to the line curve of your breast. Remember the warning signs we mentioned above: any wrinkles or sagging, move on.
How to check your bra sister-size
Finding out your bra sister-size is a great hack if you’re shopping across different brands or can’t find the exact bra size in the style you want. Often women can fit comfortably in their bra size and their sister bra size. Just like clothes, bra sizes are not alwasy universal, and fluctuate from brand to brand, but if you shop around the sizer sizes you should be able to easily find your match wherever you decide to shop.
