Yup, I don't like jackets either. They are too bulky, too formal, and as they cannot be washed easily, inclined to be a bit musty. I also don't like shirt collar corners that poke in my eye during CE dancing. I like guys to wear jeans or casual trousers with a nice, crisp, well-fitting, clean, pressed non-synthetic shirt, not tucked in. Not keen on ties. I like people to look casual and I'm not keen on elaborately formal clothing myself.
