Held to raise money for breast cancer charity Breast Cancer Now, the model made sure she stood out.
The 29-year-old’s slip was custom made from her a pink floral print from her Rosie for Autograph collection. The back of the dress featured dainty, cross-over straps and a sexy side-slit.
The slip dress has become a major fashion trend this season with the likes of Hailey Baldwin, Gigi Hadid and Thandie Newton wearing the 90s look.
Thankfully Rosie has a similar style in her current collection, so you can still get the look.
