the fashion world is yeah pretty much dictated by celebs, designers who have cred in the “scene” and some rich and powerful ppl who have interest (money) involved in the industry.
But men are always easier to up keep than women. So long as you have a nice suit or two, some dress shirts, some dress pants that aren’t too tacky looking and not too old, you should be ok.
fitting is important. Your height, body type, and hairstyle can dictate a lot of what you should and should not wear. Not to mention how you match your clothes.
Tight fitting isn’t always bad so long as it looks good on you. A v-taper is always good for men, so u wear clothes that help create that. As well as slimming lines. If you are too thin, where something that helps you look bigger to acheive the V-taper. It’s all about acheviing that “golden ratio” of beauty proportions that the ancient greeks had calculated.
If you can afford it, Armani and Boss tend to make suits for more muscular types or get a tailor to make it. D&G, versace tend to be more slim fitting and younger men, but check out the styles, your tailor can help you make it for cheaper. (I’m under 30 so I usually like those varieties) In fact, the best looking suit i got isn’t any of my boss or designer suits, rather a tailor made one (which I got real cheap in HOng Kong), that was customed to be form fitting based on the Versace slim fitting styles. But to wear those you gotta be lean…so hit the gym.
For older ppl, check out the styles of Armani, Boss, and Canali and get something similar to that style. You don’t have to get designers but u can steal their styles to see what trends are good now.
