I really do like the example you gave. It would definitely get my attention. Sorry if I stare, it's just fun to look at. However, my boyfriend can't dress that way because I'm way too casual so we'd look ridiculous. Can you imagine him standing there looking like that guy, and me next to him in yoga pants, vans, and a Luke Bryan t shirt?
Uniforms or suits, shirts with collars, tight jeans, shorts, sneakers, big jumpers and hoodies, and just seeing that there is attention to detail like watches/jewelry/ties/cool laces and stuff like that. And rolled up sleeves! I'm not too picky and it's fine if you want to wear 'sweat pants' and stuff inside the house but if you look matching/presentable/stylish outside I appreciate that.
