Both sports wear skorts and polos. The cut underneath is not the same, and the difference shows up quickly if you use one for the other.

Plenty of golf shops carry tennis, and plenty of players do both. The garments are close cousins rather than the same thing.
| Tennis | Golf | |
|---|---|---|
| Movement | Sprints, lunges, overhead reach | Rotation through the torso, walking |
| Skort length | Shorter — typically 12–14″ | Longer — typically 17–20″ |
| Built-in short | Compression, often with ball pockets | Looser, plain |
| Top cut | Racerback and sleeveless common | Collar usual, dress codes stricter |
| Session length | Intense, shorter | Four hours in the sun |
Tennis to golf: usually a problem. The skort is too short for most golf dress codes, and a racerback top will be refused at clubs that require a collar.
Golf to tennis: works better. A golf skort is longer than necessary but nothing forbids it, and a golf polo is entirely acceptable on a court. The main loss is ball pockets in the compression short, which tennis players use constantly.
Shoes do not cross in either direction. A tennis shoe is built for lateral sliding on a hard court and a golf shoe for rotational grip on grass, and each is poor at the other's job.
