A jumpsuit like this cherry red one from Stella McCartney is a smart choice to have on standby. In a slim fit, it's crafted from a compact knit with zip fastening and feminine gathered sleeves. Wide-cut legs lend extra swish as you walk – just add a pair of strappy sandals to complete the effect. Accessorize with Aquazurra pumps, a Dior handbag, and matching jewelry.
