Underbust Corset by Spanx

This underbust corset by Spanx is an innovation in corsetry minus the pulling, squeezing and restricting techniques of bygone eras.

Spanx Boostie-Yay super-slimming underbust corset features a tummy panel, boning and smart release at the hips for a comfortable fit. Reaching up to just under the bust, an invisible hook and eye closure makes for easier, less time-consuming fastening.

This Retro-inspired waist nipping underbust corset also provides sculpting power while comfortably contouring the silhouette in a chic new way.

The genius behind the brand loved by celebrities and individuals alike.

Sara Blakely (Spanx founder) was getting ready for a night out when she noticed she didn't have the right underwear to give her a smooth, seam free, look under white trousers. Armed with scissors and sheer genius, she cut the feet off her control top tights and the Spanx revolution began!

The Spanx brand now contains over 200 products ranging from shapewear and swimsuits to activewear and now men's garments! With a huge range of problem-solving products for every body type and budget, Spanx has now firmly secured a place in many women’s (& men’s) underwear drawers across the world.

SPANX shapes the world by focusing on their 1 mission: To help women (and men alike) to feel great about themselves and their potential.
