GLAMOUR's online fashion editor, Ella Alexander, examines the key celebrity looks of the day. See the five styles we're talking about on Glamour.com.
Proving that the trouser suit is a key party look this season is Caroline Issa. The wide-leg trousers give an air of Diane Keaton - all tomboyish cool - and the purple polo neck adds a pop of colour.
A stellar Buzz Lightyear-style look from rising director Gia Coppola. The dress looks like it could be worn by a little girl heading to outer space, an aesthetic we like immensely. The pleated hem detail prevents it from looking too much like a chocolate wrapper you've flattened out (why do we do that?) and the boots are so gloriously David Bowie we're already hunting for a similar pair online.
Another day, another slip dress. We're big into these for Christmas and you could do worse than take your styling cues from Rihanna - team yours with an oversized leather jacket for a tougher edge.
As anyone who has been to a high street recently will know, 70s is big - and Harry Styles has dipped in with a faux fur gilet, a cross between a fleece and sheep, and worn strangely with a T-shirt. Perhaps Styles suffers from cold that only impacts his chest, in which case this piece is just perfect.
Freida Pinto looks great in vibrant colours and there's no time when a pop of vibrancy is needed more than in murky winter. The bright yellow looks great with Pinto's berry lips too - ladylike but fresh.
