Jumpsuits are to serve as the sartorial centrepiece for one of the year's most tightly policed style showcases - Royal Ascot.
The all-in-one garment has this year been ushered into the race's rigidly enforced dress code for female spectators in the royal enclosure, organisers said.
Ladies Day at Ascot has historically been a highlight of the social season. Hats have long-been mandatory in the royal enclosure, while headpieces, hats and fascinators are required in the grandstand area.
Trouser suits paved the way for the arrival of the jumpsuit, having been given the nod from Ascot's fashionistas in 1971 - assuming jacket and trousers have matching colours.
However, the jumpsuit must be full-length to the ankle, according to the guide.
Juliet Slot, Commercial Director at Ascot, said: "The inclusion of jumpsuits as part of the Royal Enclosure dress code recognises our customers' fashion-forward taste and reflects our awareness of seasonal trends."
Exile from the event is all but guaranteed if skirts that fail to dip below the knees are worn and shoulder skin is bared. Men must also wear a shirt and tie in the grandstand.
Glamour has been known to fall by the wayside at the event in previous years, with spectators in 2016 spotted ditching their heels for flip flops and bare feet on the trackside lawn.
