It is estimated that 85% of women wear the wrong sized and style of bra and don’t even know it. Not all bras brands are cut the same. Not all breasts are made the same. Gravity, giving birth, weight changes, and just growing up make finding and sticking to a single size of bra a difficult task.

I never wear bra. I am not a person that wears woman’s clothing. WTF

Well, for you girls out there who are still wondering how to choose the bra, lets see some helpful tips.

1- Get measured by a professional. Go to any department store’s lingerie department and ask for a proper bra fitting.

2- The band (the part that goes around your back) provides 90 percent of the support, so make sure to measure your ribcage carefully. You can wear your clothing to take this measurement, but don’t wear a bulky sweater or jacket. It’s better, really, to not wear any clothes at all. These ladies have seen it all before so don’t be shy!

3- Make sure to secure the bra on the last hook (the loosest notch) when trying it on, because your bra will stretch with wear and you’ll need the ability to tighten it later. Make sure the band fits snugly, but not so that it creates a back roll.

4- Slip your shirt or blouse back on so you can be certain the bra looks and fits well under your clothing.

5- When determining your cup size, bend over at the waist and shimmy your way into the bra. This will evenly distribute your weight into cups.

6- If the band of your bra rides up your back, it’s the wrong size. The straps of your bra should not slip from your shoulders or dig into them. Straps should be about 10 percent of the support; remember, 90 percent of the support comes from the band.
