Product Insights

Spanx's Undie-Tectable Lace Support Bikini Panty delivers invisible smoothing through a bonded waistband and elastic-free edges that eliminate panty lines and muffin top, with light compression for the front tummy. The lace update transformed it from purely functional to fashion-forward, but requires cold water washing and flat drying to preserve materials, and compression loosens at larger sizes so hip fit may require sizing up for a smooth line.

Verified claims

Cotton gusset
Cotton gusset helps prevent yeast infections and moisture irritation per ACOG
Care
Hand wash in cold water (30°C max) or machine wash cold on a gentle cycle, then flat dry to preserve elasticity and shape; avoid bleach, fabric softeners, and the dryer.
Bonded waistband
Bonded waistband lies flat and distributes pressure to reduce panty-line ridges and muffin top.
Invisible heritage
Undie-tectable line offers invisible smoothing beyond just panty lines.
Invisible under clothes
Elastic-free edges and bonded waistband eliminate panty lines under clingy clothes.
Invisibility
Invisible under leggings and bodycon thanks to bonded edges; very thin fabrics may show texture.
Mission heritage
Bonded waistband and light compression deliver Spanx's founding invisible promise.
Design evolution
AW15 lace and color update transformed the panty from purely invisible to fashion-forward.
Line classification
SPANXsmooth family with built-in smoothing, not Fit-to-You non-shaping.
Compression
Provides Level 2 (SPANXsupersmooth) light compression—much lighter than OnCore's Level 4 sculpt—and smooths the front tummy without cinching the waist or lifting the butt.
Sizing
Compression loosens at larger sizes; hip fit may require sizing up for smooth line.
Invisible construction
Bonded waistband eliminates ridges; cotton gusset adds breathability and prevents irritation.
Material
Lace is 83% nylon/17% elastane for stretch that conforms without sagging; gusset is 100% unblended cotton for breathability.
Waistband design
The bonded wide waistband lies flat and is designed to stay in place, though some wearers experience rolling or riding up if the size is too small.
Cotton gusset absorbency
The 100% cotton gusset can absorb up to 25 times its own weight in water, pulling moisture away from skin during long wear.
Waistband rise
The waistband sits just below the navel, making it one of the few shapewear panties that works seamlessly under cropped tops and low-rise jeans.

Light control for softer belly

Anonymous

Light control for softer belly type. Not primarily weight based belly, but more due to child bearing, lack of exercise and age. Comfortable to wear with feminine design. Offers light tummy control without flattening behind.

They show with jeans, on the sides. That’s why I prefer the thong-they run higher on the leg.
