To customize athletic dresses with built-in shorts: (1) choose a dress length that works with your target market, (2) integrate compression shorts with a minimum 9-inch inseam for full coverage, (3) use moisture-wicking fabric for both dress and shorts, (4) add silicone grip on shorts hem to prevent riding up, (5) incorporate side pockets in the shorts layer. AOLAFREE specializes in this design. Sample: 2–3 weeks at US$ 40–80 / piece.
