Smoothing fit & size

Shapewear fit notes for visual smoothing, coverage, comfort, and measurement-based sizing.

Fit & size

Do not size down. Use real waist, hip, bust, and torso measurements so the piece can smooth without rolling or digging.

Fabric & coverage

Review the product description and photos for fabric composition, stretch, lining, padding, pockets, opacity, and care. For lighter colors, check photo coverage before choosing underwear color.

Before checkout

Confirm the Size Guide, shipping timing, and return policy. Flexvibe describes fit, support, and visual smoothing only; we do not promise weight loss, body changes, or medical results.
