Study up in the art of sexy, with the oh-so cheeky and flirty Math Club Crush school girl costume collection.

For this three-piece set, a cropped top in vibrant yellow tartan teasingly shows off the under the bust and features playful capped sleeves. A mid-rise tartan skirt flatters the hips, with a ruffled construction dancing over the thighs.

Wear with the slinky included g-string and you'll be ready to score top marks.
