The daughter of Dubawi had not been seen in competitive action since finishing a close-up third in the Prix de l'Opera at Chantilly last October and missed an intended appearance at Royal Ascot after suffering a setback.
John Gosden's charge finished fifth of six runners on the Sussex Downs, but was not beaten far by the brilliant Winter.
Simon Marsh, racing manager for owners Lord and Lady Lloyd Webber, said: "Having missed the Middleton Stakes at York because of the ground before she had this muscle enzyme problem that has kept her off the track, we had no option but to run her.
"She didn't like the ground and there was a slow pace, which didn't suit her, but she ran a perfectly fine race.
"She's come out of the race well and I'm sure she'll improve immensely. Hopefully you'll see a much better filly next time she runs on more suitable ground.
"She's in everything and has many options. John will ultimately decide where she'll go.
"There's the Prix Jean Romanet at Deauville and she's in the races at York (Juddmonte International and Yorkshire Oaks).
"We'll see where we are in 10 days' time."
