Before you buy anything, I'd always hold a cheap and an expensive piece of the same type next to each other and feel them - then you'll see right away whether there's actually a difference or if it's just marketing. For me, it's like this: years ago I bought one of those plain beige linen shirts from one of these brands because it was hyped everywhere, and honestly you wear it constantly because it really goes with everything and doesn't get all stretched out after many washes like the 20-euro version from the discount store. But that doesn't mean you always need the more expensive brand - sometimes the difference is marginal, sometimes the whole thing really just screams hype and premium pricing without any real added value. Trying things out and comparing them yourself gets you further than listening to whatever influencers have to say.
