All our super stretchy garments are designed to accommodate bumps, boobs and bums so you only need to buy one size to stretch with you all the way. And back.
If you are unsure or a borderline size, it’s always best to size down if you generally prefer a closer, more supportive fit and size up if you prefer something more roomy.
Size S/M fits a range of sizes from pre–pregnancy dress size (your usual size) 28 up to pre–pregnancy size 34.
Size M/L fits a range of sizes from pre–pregnancy dress size 36 up to pre–pregnancy size 42.
The cups on our Nursing Bra are designed to stretch from an A to a DD (that’s before nursing!) so for bras, pick your dress size and the cups will grow with you.
