Buying Guide

Choose the right length

Select boyshorts or slip shorts based on dress hemline and desired thigh coverage to prevent visible lines or chafing

Check compression zones

Look for targeted tummy-control or high-waist panels if you want shaping at the waist versus uniform smoothing across hips and thighs

Prioritize seams and edges

Seamless constructions reduce show-through under thin fabrics, while lace or silicone hems can help keep shorts in place

Consider material and breathability

Microfiber blends and mesh panels balance smoothing with airflow for comfort during extended wear

Size for comfort, not just measurements

If between sizes, choose the larger size for longer wearability; too-tight shapewear can roll or create bulges
