Naturally, this logic extends beyond the jumpsuit and of course does not require one to always make a new purchase. If you have a dress or jacket in your wardrobe that you have not worn in ages, why not dust it off and get creative with - try dressing it up, dressing it down, matching it with pieces in a similar colour palette but perhaps with contrasting textures, such as a beige pencil skirt in damask cinched at the waist with a camel leather belt.
With a bit of fashion artistry and a willingness to experiment, a single garment can perform multiple functions in a wardrobe.
