Fit 4" Body Tape

Wore this under a backless dress for a wedding and it stayed put through hours of dancing. The stretch material is sturdy but doesn't dig in, and it shaped everything smoothly under thin fabric.

I was skeptical about tape holding everything in place, but the stretch material really does conform to your shape and stays put through a whole evening. It's soft enough that I forgot I was wearing it, which never happens with bra alternatives.

Wore it under a backless dress for eight hours and forgot I had it on—the sturdy-yet-soft fabric held everything in place without pinching or rolling. Cut two strips to size and the adhesive stayed firm even through a humid evening out.
