Frequently Asked
Designed by Women for Women
We believe shapewear should do more than just make you look good it should make you feel good too.
We don’t design by starting with a size small and scaling up. Instead, we build every piece from the beginning using real size on our models, so all the shapewear, dress, and bra are True to Size so the result actually works for real curves.
Our shapewear is made to follow your shape not fight it with targeted support and sculpting that’s made to move with you, not against you.

Careguide
- Wash by hand or use a gentle machine cycle
To keep your shapewear in great condition, treat it with care. Hand washing is the safest option, but if you’re short on time, you can use the washing machine—just make sure to select the delicate cycle. - Go for a mild detergent
Shapewear is made with sensitive materials, so stick to a gentle detergent. Skip the fabric softeners and bleach—they can weaken the fabric and reduce its lifespan. - Air dry only
Avoid the dryer! Heat can break down the elasticity. Instead, lay your shapewear flat or hang it up to dry naturally. Try to keep it out of direct sunlight to prevent fading. - Store it the right way
To help it keep its shape, fold your shapewear neatly or hang it up in a cool, dry spot. Avoid cramped drawers, direct sunlight, or humid areas. - Know when it’s time to replace it
Shapewear doesn’t last forever. If it starts feeling loose, loses its shape, or isn’t offering the same level of support, it’s probably time for a new one.
