Isabella Oliver has designed its maternity clothes to match your pre-pregnancy clothing size for extra ease, giving you one less thing to think about. Many pieces are infused with their signature ruching and wrapping for a flawless fit at every stage.

Please refer to the chart below for clarification. Simply, take your pre-pregnancy clothing size and look across the chart to find your Isabella Oliver size.

So, if you were usually a UK 12 before you were pregnant, just order an Isabella Oliver size 3. Additionally, if you are a UK 14, then our size 4 is for you.

If you are in any doubt, please check against our measurement chart to find your correct size against your body measurements. Alternatively, you can also reach out to sue@hautemama.ca

Measurement Guide

Bust

Wearing a bra, place the tape around the fullest part of your bust, ensuring the tape is straight across the back A

Waist

This is the slimmest part of your natural waistline. Above the naval and below the ribcage. 

Hip

Place the tape around the fullest part, usually over your bottom or at the top of your thighs D

Inside leg

The measurement between the top of your leg (at the crotch) to the ankle. 

Arm length

With a gentle natural bend in the arm, hold the tape on your shoulder bone and measure over your elbow to your wrist. 

Expecting Twins?

If you are pregnant with twins, we recommend you go up a size. Therefore, if you were a UK size 12 (Isabella Oliver size 3) before you were pregnant, order an Isabella Oliver size 4.
