So I've picked out a couple of blazers to go with some of the outfits I've selected. The Hackett one is the same fit wise and the Scotch one is the same sort of casual jersey fabric. Do check out the rest of the shop though as there's a range of other bits that I think would be worth you seeing.
There's a few Gant chinos too! In the same fit as the ones you liked previously. Casual jacket wise I thought the Human Scales jacket would be perfect. Don't ask me why the picture looks green, it is very much navy and I promise it's beautiful in real life. Definitely worth the purchase!
