A soft bouclé tweed in deep amethyst, the colour of a gemstone turning slowly against the snow. From across a room it reads as one rich violet; come closer and the cloth opens up, flecked with navy, so that the colour seems to move as you do.

• The violet is rich and saturated, never sweet: it glows warmer by candlelight and cooler by day, and holds its depth in every light.
• The navy runs through the weave in fine flecks, giving the purple its shadow and its night, and making the jacket as easy to wear as a dark classic.
• The weave is close and even, the violet and the navy so finely mixed that the cloth looks like one deep colour until you stand beside it.
• The bouclé is looped and lively, soft and springy to the hand, and as matte as velvet from across a room, so the colour never shines but glows.
• The lining is a deep tonal silk, smooth and cool against the warmth of the tweed, so the jacket slips on as easily as a cardigan.

A neat jacket that ends at the hip, with a stand collar and an asymmetric front, cut straight and easy. Its lines are clean and graphic, and it looks as right with a slim skirt, as on the runway, as it does with tailored trousers or straight dark jeans.

• The collar stands close at the neck and fastens high with two tweed buttons, framing the face like the collar of a winter coat.
• The front wraps off-centre in a clean, graphic line, closing to one side so the jacket reads as a single unbroken plane of colour.
• The pockets are slim welts set low at the hip, each finished with a tweed button, discreet enough to keep the line perfectly smooth.
• The sleeves are straight and stop just above the wrist, leaving room for a glimpse of bracelet or a fine leather glove.
• The back is clean and straight, with a small slit at the hem that lets the jacket move with every step.
