Buying Guide

Choose the right compression level

Light to medium compression provides smoothing without visible lines under unlined pants; higher compression is better for more shaping but can show through thinner fabrics

Prioritize seamless construction

Seamless or flat-seamed shorts reduce visible edges under unlined garments and create a smoother silhouette

Look for anti-chafing fabrics

Brands that list anti-chafing or slip-short design use stretch blends and friction-reducing finishes to prevent rubbing between thighs

Consider lace trim and hem finish

Lace-trimmed edges can be decorative but may show texture under very thin pants; choose plain hems for minimal visibility

Balance fit and value

Compare sizing guidance and user ratings to find brands that deliver consistent fit and durability for the category's typical price range
