I am not a prolific clothes buyer. I plan my wardrobe, work out what garments are needed for a reasonable turnover of different outfits and buy those. I am dressing now as I have always dressed, regardless of COVID. I dress to please myself, nobody else, so since I was entirely happy with the style of clothes I wore pre-COVID why change?
As far as brand go I am prepared to look at and consider everything. My trousers usually come from Landsend, because I am narrow between groin and waist and their dropped waist trousers are a comfortable fit around the waist. Otherwise anything goes.
My current winter wardrobe includes clothes from Sainsbury's, H&M, Woolovers, Cotton Traders, Lands End, a fair trade store, East, Next, a supermarket in France, Oxfam, Sue Ryder charity shop, a hand knitted sweater, yarn and pattern form the local knitting shop, ebay.
Once clothes are no longer wanted, worn out or unfashionable they will be into the textile recycling skip or down to the local Charity shop within a week. I have very few clothes that are not worn regularly - and most of those are special occasion clothes, smart or casual.
