We're totally in LOVE with the prom-esque skirt - very Carrie Bradshaw!
Rosie got it so right when it came to her retro-style clutch bag which boasted Roald Dahl's Kiss Kiss book cover and offered a striking pop of colour.
The bronde beauty thew on a pair of bold red pointed courts which gave her clean-cut ensemble just the right about of glamour - perfect.
As always, Rosie's beauty look was totally on point. Her fresh faced, tousled waves combo set her above the rest of the guests and gave us oodles of holiday make-up inspo!
