Story & heritage

The Slim Jersey Jacket is one of Whistles’ most proven tailoring-adjacent pieces, with the official product family carrying hundreds of reviews and colourways across black, navy, ivory, grey and seasonal tones.

Materials & craft

Whistles describes the jacket as crafted from soft cotton jersey with long sleeves, a neat collar, welt pockets and a slim waisted fit. It gives blazer polish without the stiffness of formal suiting.

How to choose & style

Use it where a blazer would feel too formal: over a white tee, with a midi dress, or as a compact top layer for wide trousers. The slim waist balances loose denim and fuller skirts.
