Feeling the weight of your work Christmas lunch’s hazy dress code? Then look to Alexa Chung, who served up straight-talking style on the red carpet. Satin slips will earn you big SS16 status (yasss!) but be sure to match with oversized tailoring to make silk office approps. For final touches, ditch the rules and style 20 denier tights with heeled sandals, and don't forget to add some necessary Xmas rouge onto your lips. Yeah, you nailed it.
