Alright, just so you get an idea of my type of style, here's what I would buy.
Ducati Crosshair Sunglasses
BJJ Arlock
BJJ Mata-Leão
Men's Classic Pique Polos
Men's Henleys
Men's Waffle-Knit Henleys
Men's Layering Tees
Men's Utility Cargo Pants
Men's Cargo Pants
Men's Extra Loose Jeans
Men’s Viral (in black)
MMA Gear BJJ Flag Hoodie
As you can tell, I don’t give much thought to pants. I never have. I usually have two pairs of pants that I wear every other day.
As for colors I usually tend to like greens (olive drab), light browns, blacks, grays, etc. I have a tendency to like military type colors (and would wear camouflage if it weren’t such a touchy issue).
One thing I fear about my "style" is that it is too aggressive (all the Brazilian Jiu Jitsu stuff).
Hope this helped…
