Why do Petites wear the wrong bra size

Wearing the wrong size bra is quite common.

Research tells us that 60 to 80 percent of women do not wear the right bra size. Personally, I know what it is to be wearing the wrong bra for years.

These days I can call myself a bra lover. This is only after I learned about bra sizing and using a small bra size chart including AAA and AA cups.

I meet a lot of women with small breasts who wear an A, B, or C cup bra that’s just not right for them.

Some might need a smaller cup and some might need a bigger cup (and a change of band size). About the average UK bra size

It’s only human to stick to something that isn’t good for you, like a bad-fitted bra.

How to measure & check your sizes

When measuring, I advise women to write down their measurements. Knowing your sizes will give you control when shopping for a bra.

Depending on the bra style and brand you might wanna choose (and fit) different bra sizes.

Why knowing your sizes is important?

  • you too might fit 2 different bra sizes (measurements can be that close together)
  • you’ll learn what sizes to try
  • you’ll realize going up or down a band size will change your cup volume as well
