Stella McCartney nearly flashed her knickers while stepping out of her vehicle to attend The Hoping Foundation's Rock On benefit in London on Thursday.
That's actually a brilliant way to celebrate the first official day of summer!
The designer looked fresh and light in a purple dress of her own design that draped languidly around her body and gave a peek at her black bra underneath!
She styled the silky number with gold accessories, including a metallic clutch and skinny belt, and yellow t-strap heels.
Of course, her signature bedhead 'do was as messy as ever.
Happy summer solstice, Stella!
