Alexandra Daddario showed off her svelte figure as she posed in some black activewear on Instagram on Friday.

The actress, 35, shared a collection of snaps posing in a short varsity tennis skirt and  a bodysuit in the same colour by Alo.

She captioned her post: ‘Now I just need to learn how to play tennis.’

Alexandra stood with her arm up by her ear in one image and playfully flared her skirt out to the side in another.
