Irina Shayk poses in red bandage bikini

Irina Shayk, 29, flashed back to her younger days as she shared a vintage Polaroid snap of herself posing in a red bikini on Instagram on Sunday.

The Russian stunner, who's currently dating Bradley Cooper, 40, drew attention to her toned figure in the form-fitting suit, which she wore for a Sports Illustrated shoot.

Bare-faced Irina had her voluptuous lips on full display and let her natural beauty shine through in the snap, typically taken during a fitting.

Irina's hair was carefully tousled and tossed to one side, styled to created a voluminous look. 

Her silhouette was on full display as she curved her body against a wall.  'Early Polas..@si_swimsuit,' she wrote, name-checking Sports Illustrated magazine.
