Hey I'm new to the forum. I'm usually a pretty laid back type as far as fashion goes, i like to look good but i'm usually a jeans or shorts, t-shirt and casual shoes type of guy. I think I have decent taste in clothes, but what I really don't have a clue about is formal wear. My girlfriend is having an exhibition culminating her four year graphic design honours degree, showcasing her work with about 20 others. It's the opening night, and i'm also meeting alot of her friends for the first time so want to make a good first impression. It's being held in an art gallery, alcohol, food etc etc.. I have no idea what to wear. I want to look good but not overly dressed up, I am pretty sure suit and tie is out of the question. I'm only 23, around 6'1 and naturally lean build. I was thinking a plain t-shirt with vest/waistcoat over top? But have no idea about pants and shoes? Or should I go for a shirt? She has quite high personal presentation standards and im sure will be dressed to impress so i'd like her to notice i'm making a bit of an effort. Thanks for your help!
