How to Choose Underwear for a Flat Bottom

What makes underwear curve-enhancing?

Look for padding (removable or built-in), ruching down the center back, and structured lifting zones that mimic gluteal curves.

Seamless vs. Seamed: What’s better?

Seamless tends to vanish under clothes—ideal for leggings and silks. But seamed options can offer better lift and shape.

Can shapewear help if I have no curves?

Absolutely. Strategic compression and cut can mimic the illusion of curves while offering comfort.
