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.

01-The Mechanism

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.

2-ply construction — double layer at the waist gives smooth, even hold without a single pressure point

No hardware — zero elastic, wire, or rigid bands to cut in throughout the day

Tubular knit technology — the waistband isn’t sewn on. It’s knitted as one continuous piece, so it can’t roll or bunch

308 Smoothing at Waist Brief — Chocolate, arms raised lifestyle shot

02-The Fabric

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.

No visible panty line — seamless finish sits flat under any outfit

Moisture-wicking — cooling fabric treatment keeps you fresh from morning to evening

Level 1 shaping — enough to smooth, never enough to restrict. Not for special occasions. For every day.

03-The Fit

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.
