No one knows your body better than you, so together with the help of The Mutha Project chart and questions on your body shape, we will find your perfect fit. 

Bras

Seam and wire-free bras fit very differently as they have a more comfortable, less structured fit. If you are confident in your size, you can go ahead and use the chart below. 

If you feel your breast shape is very full, we would suggest sizing up, particularly in the Plunge which offers less coverage. Also, if pre pregnancy you were a comfortable 32C for example, you can see from the chart below you would be a the top end of a size 1- we would suggest choosing a size 2. If you have zero idea (most of us don't) then use the easy calculator below under this chart.

If you have no idea what your size is, you can use the easy bra size calculator below;

1. Measure around the fullest part of your boobs in inches- write down the measurement

2. Measure the underband (under boob area) in inches- write down the measurement

3. Take away the underband measurement from the bust measurement. Using this number look at the chart below to see your size. Then revert to the chart above to see where you sit in Mutha.

Example: Bust 36 inches - Underband 32 inches = 4 inches difference = 32 (underband)D

Knickers

Our knickers are also cross sized, so can accommodate bumps and with the clever warp knitted fabric, can stretch and recover. The warp-knit fabric stretches with your bump and gently recovers after birth.

Size 1 8-10

Size 2 12-14

Size 3 16-18
