Sizing & Fit


The Fit  

Ilouity pants are born out of many iterations working with denim experts and designers to perfect the best fit pants for women both pre- and post-partum. Our pants have curved waistbands, low in the front to make space for the belly and slightly higher in the back for a more comfortable feeling when seated. The denim is stretchy yet mid-weight, not compromising on the quality denim feeling. The belly band is selected specially to support the back and belly through all four trimesters. We have also built the waistband such that you have space between the band and the waistline to tuck in your shirt. Ilouity pants are made to give you a look that doesn't have to be different than your pre-pregnancy one and a pair of pants you are not going to want to take off.

How Can I Find My Size?

We've tried to keep the sizing as simple as possible so you can easily find what fits best - both during and after pregnancy. Below is a size chart that should help get you to the right size.


ILOUITY SIZES (EU) 34 36 38 40 42 44 46 48
DENIM SIZES 25-26 27-28 28-29 29-30 31-32 32-33 33-34 34-35
ITALIAN 38 40 42 44 46 48 50 52
U.K. 6 8 10 12 14 16 18 20
U.S.A 2 4 6 8 10 12 14 16
BODY MEASUREMENTS (cm)              
WAIST 64 68 72 76 80 84 88 92
SEAT 90 94 98 102 106 110 114 118

While we provide a "waist" measurement above, the waistline is changing throughout the pregnancy and our belly band is meant to take you through all months of the pregnancy and postpartum so you do not need to buy different pants for different stages of the waist/belly - unless you change sizes around the seat or legs. 

Length of the pants are often in standard measurements of 30, 32 and 34 inches and are noted in the product pages where different. This is the inseam measurement of the pant and is shown below.

Please note that the specific fit description can be found in the details section under each product. We are proud to have found materials that are very stretchy and comfortable so even if you feel you are no longer your pre-pregnancy size, we encourage to you buy that size when buying Ilouity jeans.
