How to determine your bra size:

How to tell if your bra fits:

 

If you are not happy with the fit of your bra it's worth getting fitted professionally so that you know what a correctly fitting bra should look like.

If you are happy with the bra size you are wearing please stick to your normal bra size when ordering from What Katie Did.

If you're placing your first order with What Katie Did it is worth quickly checking your band size. Simply measure firmly around your ribcage just below the bust. Now you need to add 4/5 inches. For example if you measure 31" your band size will be 36. Hopefully, this will be the same as the size you're currently wearing!
	If, there is a discrepancy; for example, you've always worn a 34C but according to our measurements you should be wearing a 36; then you need to also change your cup size. If you go up a band size you need to go down a cup size so you'll need a 36B.

Still confused? The same cup size is used for different back sizes. If you go up a back size, you need to go down a cup size. If you go down a back size you need to go up a cup size. This is the same for both traditional and modern graded bras, so you can swap between manufacturers easily once you know what method they use (and this is easy, as you just need to measure the band of your bra as worn).

A 32DDD will have the same cup as a 34DD, 36D, 38C, 40B.

A 32DD will have the same cup as a 34D, 36C, 38B, 40A and so on.

To make things even easier we've put the band measurements of each and every one of our bras in the 'Size and Fit' section, just click the tab at the top of the product card.

Our bullet bras have virtually no stretch which means that choosing the correct back size is very important. In addition, the full cup means that the correct cup size must also be chosen!  Unlike underwired bras, the centre section of a soft cup bra does not always sit right on the chest, especially with larger sizes, but you should definitely have two defined breasts and not a monoboob!

Unlike modern bras, your breasts might need some adjustment when wearing a bullet bra. Once you've put your bullet bra on, lean forward to maneuver your breasts into the cups.
