She is a true English rose famed for playing the beauty in a host of hit films.
And Tamsin Egerton was showing off her naturally stunning good looks as she joined the stars at the Jimmy Choo 20th Anniversary and Pret-a-Portea book launch at The Berkeley Hotel in London on Tuesday.
The 27-year-old Love, Rosie star wore a flirty mint green marieprom dress which made the most of her endless legs while she kept her make-up and hair extremely natural.
Tamsin looked sensational for her turn at the bash where she masked her sensational figure beneath her billowing mini dress.
Clearly revelling in the last hints of summer, the mint green hue and blurred print made the look super fun and flirty.
She boosted her statuesque height with the addition of thin strapped heels, which lengthened her legs and added to the chic ensemble.
Tamsin, who welcomed her first child with actor boyfriend Josh Hartnett, 37, in late 2015, wore her blonde tresses in a volumunious blowdry while her make-up was dewy and natural.
Other stars heading to the bash included superstar offspring Amber Le Bon who went for chic retro vibes with a blue and white dress designed to look like a skirt, shirt and bolero.
Nipping in at her tiny waist, the Fifties-inspired look fell into a stunning prom style skirt which only added to her vintage sweetheart look.
Her black waist belt matched her strappy heels and leather handbag as well as complementing her black piping on the bolero top.
She posed at the bash alongside her ageless mother Amber who went for an Eighties style gown adorned with many prints and patterns.
Sandra Choi, who is the creative director of J. Choo Limited and niece of Choo's wife Rebecca, looked stunning in a patterned dress as she posed alongside statuesque Erin O'Connor.
Speaking of the event, Sandra said: 'The Berkeley’s Prêt-à-Portea has become a well-loved institution for fashion insiders and we are thrilled to take this opportunity to celebrate a key moment for our brand and The Berkeley, with a fashionable take on the great British tradition of tea.'
Supermodel Erin wore a checked dress while she slicked back her newly sheared fringe, which gave her fresh face a glowing look.
Lady Kitty Spencer opted for a flirty lace gown with a chic Peter Pan collar in white which stood out against the black body.
Australian photographer Candice Lake looked low-key in a pink jumper and loose-fitting cream skirt.
