Whistles Selena Silk Top, Pale Pink, 14

With just enough frill to make it playful, the Selena blouse from Whistles is your answer to smart workwear you can pull on when the weather heats up. The sleeveless cut is framed with a round tie neckline topped with frilled detailing, while the canvas is minimalist and endlessly pairable. Slip on with tailored trousers or shorts, and even if you do happen to find yourself in a bar after you clock off, the silk canvas won't make you look out of place.
