A recent market survey shows that nearly 80% of women may wear inappropriate underwear every day.

Below are 5 key points to remember when looking for the perfect fitting bra so you are left comfortable, confident and supported.

1) The underwires should clear the breast tissue

The underwires shouldn't be digging into the sides, nor should you be bulging over the top (ie: double boob). At the same time, there shouldn't be any empty space either. If you're bulging, you need to go up a cup size and if you feel as though your bra is the equivalent of a packet of walkers (more air, less filling) then try going down a cup size.

2) The centre of the bra should fit snugly against your breast bone

The centre should sit flat and not pull away from your body, if it does, try going up a cup size. However some women who have closer set breasts may struggle with this, if that is the case for you, try a different style and get as close to perfect as you can.

3) The band should feel firm, but not restrictive

You need the back to be firm in order to get the maximum support. Generally the rule of thumb on a new bra is to start on the loosest hook. This is so as the bra slackens with age and use, that way you still have 2-3 other hooks to fall back on. It shouldn't feel so tight that it's digging into your skin, if this is the case try a bigger band size. The same goes if you immediately go straight to the tightest hook, try a smaller band size - you don't want the band to be riding up your back making your girls at the front droop.

4)  The back and front of the band should be at the same height and even.

Take a look at yourself sideways on in a mirror. If the band is going up your back and your boobs are going south, try a smaller band size (if the cup fits, remember to go up in the cup). If the band is too tight, go up a band size and down in the cup.

5) Your straps should not be digging in nor be slipping down

Generally we say, an inch of play (stretch room) at the top of your straps is good. You don't want your straps to be digging in and leaving huge dents in your shoulder. At the same time, nor do we want them to be so loose that they are slipping down (never a good look even if the straps are pretty!).
