Size Guide

Mama Movement is on a mission to spread body positivity, and to show that healthy and beautiful comes in all shapes and sizes. As we grow as a business, we pledge to grow the size range as well.

The charts below show the approximate body measurements for each size to help you find your fit. They are NOT the measurements of the garments. 

For leggings, we recommend following the larger size according to your WAIST or HIPS measurements and sizing UP if you are in between sizes. 

For maternity leggings, measure the HIPS measurement under your bump and don't worry about the waist measurement! Our maternity leggings have an extra long, extra high waistband for your growing bump.

For sports bras, crops and outerwear, follow the BUST measurements and size DOWN for a more compressive fit or size UP for a more relaxed fit.

Bust and Hips measurements are taken at the fullest part of your bust and hips, whereas Waist measurements are taken at the narrowest part of your waist.



Our best-selling leggings come in a few different lengths. The below table shows the inseam length per size for each Legging Style. Our most popular length is the 7/8 length which looks great on women of all heights for a year-round style. The full-length is most appropriate for women over 165cm and for the colder months. And in warmer weather, check out our 3/4 or biker shorts styles!

Our baby and kidswear runs true to size. However, if in doubt, please size up as we cannot accept returns or exchanges of kidswear due to change of mind or incorrect sizing being ordered.
