Sizing Guide

How To Measure

Measure your waist and hips and compare to the size chart below. If you are between two sizes, we suggest selecting the larger size.  sizes correspond to the numerical sizing on this chart, unless specified in the description of the garment. To get the most accurate measurements, have someone else measure you. Be sure to hold the measuring tape straight and snug, not tight, to your body.

BUST

Measure over the fullest part of your bust, with the tape measure parallel to the floor. This measurement will assist you in determining your clothing size for tops/bras.

UNDERBUST

Measure directly under your bust at your ribcage, with the tape measure parallel to the floor. This measurement will assist you in determining your bra band size.

WAIST

Measure around the narrowest part of your natural waistline.

HIPS
Measure around the fullest part of your hip, before the thigh begins to narrow. This measurement will help you determine your size for shorts, pants, and Thigh belts.

No. Our FupaEraser and Full Torso Vests are not designed with sauna fabric / sweat technology. Though you can sweat through increased movements, they are suitable to wear while running errands or wearing outside of workouts.

Our sweat belt is designed with our sauna / sweat inducing technology and our compression belt is not.

Differences: 

Sweat Belt: mainly used for active support, waist slimming and interval training. Has neoprene sweat technology built in.

Compression Belt: is designed to support moms after child birth. Mainly used after C-section or vaginal delivery during recovery period.

Similarities:

  • Both belts are designed to wear during postpartum.

You can start wearing it immediately after you deliver, but please check with your healthcare provider prior to use, especially if you’ve had a C-section.

We recommend wearing it no more than 6 hours a day for 8-12 weeks after birth to encourage abdominal recovery, proper posture and helping prevent back pain during breastfeeding.

If it has been a few months since delivery and you're feeling more comfortable to begin belling binding, we recommend our FupaEraser or Full Torso Vest.

We do not recommend wearing any waist trainer or belly binding garment while sleeping. This safe practice allows you to monitor if you grow uncomfortable or have shortness of breath to immediately stop use.

Do not machine wash. We recommend spot cleaning by hand with soap and water. Lay garments out to air dry.
