Straitlace was a British Thoroughbred racehorse and broodmare. As a two-year-old she was one of the best fillies of her generation in England when she won five of her eight races. In the following year she finished third in the 1000 Guineas before going on to win the Epsom Oaks, Coronation Stakes and Nassau Stakes, as well as three other races. She earned more money than any other horse in Britain in 1924 and was retired after winning eight of her sister races. Straitlace was exported to France in 1925 and became a very successful and influential broodmare.
Straitlace ran consistently against good competition as a two-year-old in 1923,recording five wins, two seconds and one third place from eight starts. After finishing second to Mumtaz Mahal at Newmarket Racecourse in May she won the Stud Produce Stakes at Sandown Park, the Great Surrey Foal Plate at Epsom Racecourse, the Exeter Stakes at Newmarket, a Rous Memorial Stakes at Goodwood and the Autumn Breeders' Foal Plate at Manchester. At Newmarket in October she finished second to Chronometer in the Cheveley Park Stakes. On her only other appearance she finished third to Eatonwick and Heverswool in a Rous Memorial Stakes at Newmarket. By the end of the year she had earned at least £6,175 in prize money.
1924: three-year-old season
On 9 May 1924, Straitlace was one of sixteen fillies to contest the Rowley Mile course at Newmarket Racecourse and finished third behind Plack and Mumtaz Mahal, beaten two lengths by the winner. At Epsom on 6 of June, Straitlace faced a rematch with Plack in the 146th running of the Oaks Stakes. Thecontest was run in fine weather but attracted a smaller than usual crown, with many racegoers reportedly being discouraged by the appalling conditions which had prevailed for the Epsom Derby two days earlier. Ridden by Frank O'Neill, she started at odds of 100/30 second favourite in a twelve-runner field. Straitlace tracked Plack in the early stages before overtaking her rival approaching the straight and then opening up a clear advantage. She won by one and a half lengths from Plack with the fast-finishing Mink a head away in third place. At Royal Ascot in June Straitlace was brought back in distance for the Coronation Stakes over one mile in which he was ridden by Charlie Elliott and won at odds of 3/1, "in the style of a really good filly". At Goodwood, with Elliott again in the saddle she started 4/9 favourite and won the Nassau Stakes over ten furlongs. The runner-up on this occasion was the Aga Khan's four-year-old Charley's Mount, who went on to win the Cesarewitch later that year. She won three other races in 1924 and was retired at the end of the season having earned £17,965, making her the most financially successful horse in Britain that year.
Assessment and honours
In their book, A Century of Champions, based on the Timeform rating system, John Randall and Tony Morris rated Straitlace an "average" winner of the Oaks.
Breeding record
Straitlace was retired from racing to become a broodmare. After Edward Hulton's death in 1925 the mare was sold for 17,000 guineas by Edward Esmond. She was exported to France where she spent the rest of her life. Her foals included:
