Is this real workout gear or a costume?

It is a costume-styled set. Treat it as fan and cosplay wear and light exercise, not as compression or technical training clothing.

Can the leggings and top be worn separately?

Yes. Each piece is a standard leggings or crop top shape, so you can pair either with your own clothes.

Sizing follows a generic chart rather than athletic fit. Check the measurements against a pair of leggings you already own before choosing.

The set is styled as a Harley Quinn costume look across the leggings and crop top. Exact print placement depends on the version you receive.

Yes. That is its main use, and it is easier to move in than many packaged costumes.
