Black Caviar's little sister Belle Couture could make her long-awaited racetrack debut in the next week.

Trainer Danny O'Brien said the filly was likely to be nominated for races this week with a decision still to be made whether the three-year-old has another jump-out on Friday or heads to the races.

"She's not far away. We'll probably nominate her for a couple of races next week," O'Brien said.

A country maiden is the likely starting point for the high-profile daughter of Redoute's Choice out of Helsinge.

"It's either give her another trial or go to a country maiden. And I'm tipping towards taking her to the races providing we can get to the right race," O'Brien said.

The Flemington trainer said Belle Couture worked nicely on Saturday morning and was fit enough to go to the races.

The filly has had two jump-outs at Flemington in the past month and won her most recent one last Friday week.

Belle Couture was knocked down to BC3 Thoroughbreds for $2.6 million at last year's Easter Yearling Sale.

BC3, which is now in voluntary administration, is still listed as a shareholder in the filly.

The first meeting of BC3 creditors will be held on Thursday, a day before former chairman Bill Vlahos is due to return to the NSW Supreme Court where he is being sued for $26 million by a company which invested in his punters' club, The Edge.

Moore Stephens, the administrators of BC3, say there is no link between the company which races horses and the so-called punters' club run by Vlahos.

Belle Couture is a half-sister to champion mare Black Caviar, unbeaten in all her 25 starts.

The filly is also a half sister to multiple Group One winner All Too Hard.
