[5] At the end of the month she was stepped up in class for the Listed Debutante Stakes over the same distance at Leopardstown Racecourse and won again, beating Priory Belle by one and a half lengths at odds of 4/6.
On 19 June, she was sent to England to contest the Coronation Stakes at Royal Ascot and led for most of the way before being overtaken in the final furlong and finishing third to Shake The Yoke and Last Second.
The other four runners were Shamadara (Prix de Malleret), Key Change, Tout A Coup (Cheshire Oaks), and French Ballerina (later to win the Supreme Novices' Hurdle).
The French filly rallied strongly and appeared to regain the lead, but Dance Design came back again in the final strides and won by short head.
[9] After a two-month break, Dance Design returned for the Irish Champion Stakes over ten furlongs at Leopardstown in which she was matched against older horses and male opposition.
Carrying top weight of 130 pounds she started odds-on favourite and on by a short head from Raiyoun with a gap of ten lengths back to Tout A Coup in third.
[10] Three weeks later, over the same course and distance, the filly faced stronger opposition in the Group 2 Tattersalls Gold Cup but her task was made considerably easier when the favourite Dr Massini refused to race.
She led from the start, accelerated away from her six rivals in the last quarter mile and won by two and a half lengths in "impressive" style despite being eased down by Kinane in the final strides.
[12] She was then sent to Germany for the Bayerisches Zuchtrennen over 2000 metres at Munich on 3 August but after leading for most of the way she was overtaken in the closing stages and beaten half a length by the locally trained five-year-old Oxalagu.
