Butter. Form. Pulse.
Made for the way you move.

Shared DNA
Every piece shares this DNA.
The Fabrics
Our fabrics are designed for the way you move.
Movement is at the core of everything we do. Each fabric was developed with intention, chosen for how it feels against the skin and how it carries you through your day.
Butter
Our most indulgent fabric.
Buttery soft, barely there, impossibly comfortable against the skin.
Buttery soft. Smooth. Cozy without being heavy.
The softest, stretchiest of our three with a gentle hold. Most pieces fit true to size. Our sculpting styles in Butter hold firmer, so if you're between sizes, size up.
Form
For every moment in between.
Smooth and sculpting with a firm, held-in feel. Carries you from morning to everything after.
Firm, smooth, breathable, second-skin.
Firm and sculpting, so it fits snug. Stay true to size for a held-in feel. If you're between sizes or want more give at the waistband, size up.
Pulse
Built for movement.
Light but serious. Compression that lifts and holds without heaviness.
Lifted, sculpting, strong.
Our highest compression, so it runs snug by design. Stay true to size for full compression, or size up for a firm but more relaxed hold.
Size & Fit
Find your fit.
Our sizing guide works hand in hand with our fabric guide to help you find the right fit and feel. Use the chart as a starting point, then check how your fabric fits.

Compression vs. stretch.
How much the fabric gives as you move. More stretch means a softer, easier fit.
How firmly the fabric holds you in. More compression means a snugger, more sculpted fit.
The higher the compression, the snugger the piece will feel in your usual size.
Soft with a gentle hold. Most pieces fit true to size. Sculpting styles hold firmer, so size up if you're between sizes.
Firm and sculpting, so it fits snug. Size up if you're between sizes or want more give at the waistband.
Our firmest hold and our snuggest fit. True to size for full compression, size up for a more relaxed hold.
Between sizes?
Size up. Every AIVVIA piece is designed to fit close to the body, so when in doubt, the larger size is the safer choice.
For Butter, your usual size works for most pieces. Size up for a softer, more relaxed feel.
For Form and Pulse, expect a snug, held-in fit. Size up if you prefer more room or less compression.
