I'm pretty ruthless with clothes, but, I'm also very considered with purchases, I don't buy clothes that I either don't love it are not filling a necessary gap in my wardrobe.
Plus, if I need a skinny-rib polo-neck or a a white t-shirt, I'll buy the absolute best I can afford and I know looks great, ergo I'll only have one of each item as I know I'll always go for the one that looks best, so why have multiples?
That way my wardrobe is actually very compact, never needs a cull, and I can make loads of different looks from relatively few clothes.
And it's not a 'uniform' either, which is a criticism often levelled at fairly paired-down wardrobes, it's more a case of finding the right stiletto, or flat, or boot or trainer that can completely change the mood of an outfit even if you were to wear exactly the same above the foot!
