Posting the black and white snap on Instagram, Chung shared her delight in being included in the latest series on Tuesday 9 May.
“Thank you, Mario Testino for including me in your ‘Towel Series’,” she wrote.
The legendary photographer also shot the presenter-turned-model for British Vogue’s June cover.
Wearing a gold sequinned beret and striped top, Chung looks incredible.
Taking to Instagram, the British It-girl posted an image of the cover, saying:
“Ah, thank you British Vogue and Alexandra Shulman for having me as your June cover girl!
“Check out inside the issue for a sneak peek at my forthcoming @alexachungstagram summer collection styled by Lucinda Chambers. Beyond grateful to all involved: @mariotestino.”
Inside the June issue the publication shares a glimpse of Chung modelling some pieces from her first clothing line, Alexachung.
Taking to Instagram, the creative director shared an image from the issue on 10 May, with the caption:
“Wearing @alexachungstagram knitted top and sequin dress, styled by Lucinda Chambers.”
We’re hoping to see the fashion icon’s take on her staple frilly blouses, dunagrees and classic granny knits.
