I don’t think that’s particularly true. There’s a lot you can do with texture, colours and silhouettes, even within items that are “the same”. I do think most men are pretty unimaginative when it comes to dressing themselves though, and most can’t even do basic things like getting trousers hemmed to fit them properly.
Never forget the Australian newscaster who wore the same suit for a year and no one noticed/called him out for it. His broadcasting partner, a woman, had been called out for wearing the same outfit previously. There may be subtle variations available to men, but the simple fact is that many fewer people notice or care.
