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.
I’m a lady but once I went to Target for clothes and came back with 4 bottoms all the same dimensions but the sizes were 4, 5, 7 and 9. All of those were the same size somehow.
