For men, as mentioned, the t-shirts and vests and leather jackets and outerwear. I don't know if he does the silk knit t-shirts year round, or just for A/W, but they're nicer, last longer and are seemingly less prone to holes, which I've found to be a problem with the cotton knits. From what I remember, they were a similar price to the cotton as well, but just go with the plain ones and avoid any printed or appliqued ones, as they never seem to sell well. I'm surprisingly excited about the double layer t-shirts I've been seeing recently, I don't know if they're new, but I really like the idea. Also for men, those buttonless cardigans like this one:
Sold crazy well when I worked at Liberty, but the rest of his boiled/felted wool pieces for men tend to be a bit, um...ugly. He also does really beautiful sharp suiting that a lot of retailers don't buy, which is a shame because it's really well constructed, and quite unexpected from him. Some of the DRKSHDW jeans are nice, and I like his trainers.
But Leyla you've got great taste, so whatever you buy will be amazing.
