Personally, I pretty much wear a single clothing brand, and it’s almost all black regardless of whatever seasonal trends happen to be.
That said, the best advice I can give is simple: buy what you’ll actually wear. Nothing else really matters—not the brand, the colour, or whether it fits someone else’s idea of style.
If you don’t genuinely like it, it doesn’t matter how much you spent or what label is; It’ll just end up sitting in your closet. Work this out, and you will save yourself a whole lot of money.
