When I took French in high school, we did a unit on clothing. Included in the garment names we had to memorize was one of my favorite french words: Jupette. My text book defined it as "tennis dress," but it can also be used more generally for a short skirt.
Given the sticky hot weather mother nature has been treating us to, I think celebrating jupettes and the baring of legs is most appropriate.
Vintage Tennis Dresses are always so awkwardly explicit about what they are to be used for.
While modern ones, like this one by Stella McCartney, are cute always. But I think that shorty short skirts should be rocked off the court too...
....even to a fancy soiree...
....Or in outer space!
