Smoothing that disappears under everything
Our founders spent 30+ years designing for Victoria’s Secret, Nike, Spanx, Lululemon, Triumph, Maidenform and more. They built the 308 Brief to solve what no other underwear had — a waistband that smooths without digging, shapes without compressing, and disappears under any outfit.
Every Detail, Designed with Intention
Three decades of intimate apparel expertise went into every stitch. Here’s what makes the 308 Smoothing Brief different from anything you’ve worn before.
The Waistband That Holds Without Marking
Most waistbands do one of two things: dig in and leave marks, or sit loose and do nothing. Ours does neither.
The 2-ply waistband is engineered at the yarn level — not compressed onto your body, but knitted to sit flat and hold. No elastic bands. No hard edges. No red marks when you undress.
Second-Skin Feel. All-Day Breathability.
We don’t call this shapewear. That’s not an accident — traditional shapewear compresses. This fabric holds its shape around you, not against you.
The result is something most women describe the same way: you forget you’re wearing it. Your waist doesn’t.
Seamless Silhouette
No raised seams, no visible lines, no panty outline under clothes. The 308 disappears under everything — fitted dresses, tailored trousers, lightweight fabrics. You'll forget you're wearing it. Your clothes won't show that you are.
