How they smooth without squeezing
Four details working together, so your tummy looks smooth and you can still breathe.


Criss-cross front panels
Two bands cross over your lower tummy and gently hold it in, right where the mom pooch sits.

A high waist that stays up
The wide band sits just under your ribs and stays flat when you sit, bend and run around all day.

Full-coverage back
Cut to stay where you put it. No riding up, no wedgie.

Breathable mesh and a cotton gusset
Mesh panels let air through, and the cotton gusset keeps you fresh from morning to night.
Same outfit. Smoother line.
Left: everyday underwear. Right: the same outfit with Sielvane Panties underneath.

Before you ask
Do they roll down or roll up?
No. The high, wide waistband stays flat against your tummy, and the legs are cut to lie flat, so they stay where you put them.
Do they ride up or give you a wedgie?
No. They have a full-coverage back that stays in place all day, even when you sit or bend.
Will they show under tight clothes?
They're made to sit smooth under leggings, jeans and fitted dresses, with no lines or bulges. Beige is the most invisible under light colors.
Are they comfortable enough for all day?
Yes. They're soft, stretchy nylon-spandex with breathable mesh panels, not stiff shapewear. You'll forget you're wearing them.
Is there a cotton gusset?
Yes, every pair has a cotton gusset.
How do I pick my size?
Go by your weight in the size chart. If you're between two sizes, pick the bigger one for all-day comfort.
