This black Nico bodysuit from Tatu Couture, made right here in Britain, is one of those pieces that just nails 'smart-sexy'. It’s a sheer, long-sleeved number with delicate polka dots, giving it a bit of an edge without being over the top. The pussy bow is a great touch, done in a statement silk georgette, and you can totally remove it for a cleaner, more minimalist vibe if you prefer. I'm thinking this works for pretty much anything. Pop it on with some sharp trousers for an evening out or a special do, or even layer it under a blazer for work when you want to feel properly put-together and confident. For a date night, a sleek skirt would complete the look. It's a slim fit, made from a mix of silk and polyester, so it feels good against the skin while holding its shape.
