The three-year-old, who is the only British-trained runner in the field, will take on seven rivals in the mile contest as she bids for a sixth win since the start of the year.
After claiming a Listed victory on her penultimate outing at Sandown, the daughter of Dream Ahead subsequently finished third in a similar heat at Ascot.
Elsworth said: "She is in good form and has progressed all season. I think she has a realistic chance.
"She is a tough little thing and always saves a bit for herself and this time she has got the services of Ryan Moore.
"I thought the race at Sandown was softer than the one at Ascot. I thought she ran encouragingly at Ascot and she was not beaten far.
"I thought that race was at least a Group Three in disguise. This race doesn't look fantastic on paper, but you must tread carefully as you don't want to underrate the opposition as it can come back and kick you."
The Henri-Francis Devin-trained Charm Appeal will be making her first start since finishing down the field in the French 1000 Guineas, while Andre Fabre will rely on Esquisse and Lady Frankel.
Completing the field is Monroe Bay (Pascal Bary), Silver Storm (Christophe Ferland), Limited Edition (Elie Lellouche) and Enlighted (Freddy Head).
