Whilst we've seen the jumpsuit become a catwalk staple for some seasons now, the key to buying an investment to last Summer through to Winter is to look for a long sleeved, long legged one-piece. Keep it belted to accentuate the figure and buy in neutral colours, sticking to black, petrol blue or nudes and pale greys. Accessorize with shoe boots for day or stilettos for night, and even an oversized pompom if you're feeling brave a la Sonia Rykiel.
