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
Wash in cold water (30°C max) and flat dry to protect lace and elastane.
Bonded waistband
Bonded waistband stops panty lines 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
Much lighter than firm shapes like OnCore; smooths only the front tummy area.
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.
Lace evolution
Spanx added lace to its Undie-tectable line in AW15, turning purely functional shapewear into a fashion piece meant to be shown off.
Material
Lace is 83% nylon/17% elastane for stretch that conforms without sagging; gusset is 100% unblended cotton for breathability.
Waistband design
Bonded wide waistband stays flat and avoids rolling.

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.
