The model, 27, was reunited with fellow Strictly Come Dancing contestant Julien Macdonald when she wore a dress designed by him especially for Fashion For The Brave at the Dorchester hotel, Park Lane, London.
Showing off her super-slim frame, footballer's wife Abbey wore a Union Jack dress with silver tassles - which wouldn't have looked out of place on the Strictly dance floor.
But few people's eyes would have been on the dress itself, as Abbey's side boob and torso were also on display in the revealing dress which had sheer side panels.
In the lead up to the event, Julien tweeted: "Getting ready for this evening with @OfficialClancy Sparkling in my dress, you look stunning!"
Meanwhile, Abbey described the dress as "amazing".
Fashion For The Brave raises money for the Household Cavalry Foundation and Soldiering On. Every year, the grand finale features a custom-made dress by a top designer - this year Julien designed the dress modelled by Abbey.
Liverpudlian Abbey - who is married to England footballer Peter Crouch - is bookies favourites to win this year's Strictly with her professional dance partner Aljaz Skorjanec.
