As a 6’2 man the clothes I find which are right for my height are often very loose on me. And if I worry about the waist I look like a kid who grew a lot in the past 2 months and everything is too short for me.
Its not entirely universal, some stores are better than others. And I wear a lot of loose casual t-shirts so thats fine too. But finding dress shirts means some places work, some don’t.
If you buying more expensive trousers then you can have the waist tailored to reduce it. I typically buy 40" and have them reduced to a 34". Obviously, this isn’t worth doing if you buying half a dozen for £50 from h&m or similar budget trousers.
