Catching up @ToastCosILoveIt belated thanks for info about the Barbour blouse material! Sounds like it will be too thin in the dress version, so I will stalk the blouse.
No code for me either, and I too remember when early-season codes were standard for Kindred @OftenOrange
Adding to list of brands @SealDeal good high street basics can be semi-reliably found at Muji and Uniqlo. If you like the more utilitarian side of Toast, YMC, Folk, Studio Nicholson, J&M Davidson. More wafty/oversized: Oska.
You mentioned Arket but I think COS has overtaken it, especially this year. (Though I may change my tune if they cancel the coat I managed to order in the 3 seconds it was in stock.)
