Integrated Shelf Bra
Built-In Shorts Liner
Full Rotational Range
The Baseline Dress is a one-piece performance tennis dress engineered for the actual biomechanics of a tennis swing. A fitted bodice with integrated shelf bra, a flared skirt panel with built-in shorts liner, and a premium technical knit cut for full rotational range of motion. British-designed with a feminine hand, in a restrained court-appropriate palette. No separate bra. No separate liner. No adjusting between points.
If you have ever chosen between looking good and playing well, this dress ends that trade-off. Knightley treats aesthetic precision as a performance specification, not an afterthought. Integrated construction eliminates the three-piece kit problem entirely, the technical knit moves in rotational arcs rather than just forward motion, and the proportions are cut for real women across a full size range. You should not have to change after your match. This is the dress you wear all day.
Complete freedom of movement through every swing and serve. Integrated shelf bra and shorts liner mean one piece does the work of three. Skirt panel stays in place during play. Streamlined silhouette that reads polished on and off court. Restrained British palette, sharp without shouting. Proportioned for real women, not a single athletic silhouette.
Wear as a complete one-piece kit. The integrated bra and liner are built in, so no layering is needed. Size using the Knightley fit guide for your best match across bust, waist, and hip. Most customers find their regular size fits true to the technical knit.
Every Baseline Dress order is covered by our 30-day satisfaction guarantee. If the fit or performance does not meet your expectations, contact us and we will make it right, no questions asked.

Women who wear The Baseline Dress stop choosing between playing well and looking the part.
Every element of The Baseline Dress is built with a specific job to do on court.
Moves with your swing, not against it. Cut for the rotational arcs of a real tennis stroke, this fabric stretches in every direction without pulling, bunching, or losing its shape.
Stay composed through every set. A performance inner layer draws sweat away from the skin so you feel dry and confident from the first warm-up game to the final changeover.
Secure support without the extra layer. An integrated shelf bra with removable padding gives you a clean, confident fit, no separate sports bra required.
Step on court ready to play. A built-in shorts liner with a dedicated ball pocket means one piece handles everything, so you can focus entirely on your game.

“Holds up through back-to-back sessions, mostly Wore it six sessions straight, washed it four times, fabric still looks good. The built-in shorts ride up a bit when I'm moving at the net, which gets old fast.”

Wore this back-to-back against my Nike and Wilson dresses. Four-way stretch is comparable, compression skirt stays put, and the shoulder seams dont dig in mid-match.
Bought it thinking it would sit in my bag like my motivation does. Fits well, moves fine, and I've actually worn it twice already.
Wear it from warm-up to the bar. No complaints.
