I don't want to wear teen stuff I want something a little more mature. I have never been good with style so I don't know what girls like.

I think your clothing should reflect your lifestyle, ie if you're sporty, wear sporty stuff, if you're in business or some white collar job, wear business casual stuff or if you're just casual, a nice polo or t-shirt with jeans will do well, provided that the t-shirt is clean (style wise) and not laden with logos or gangster art. Personally, I like the business casual look because it makes a guy look successful and modern.
Shirts: polo, simple clean t-shirt, dress shirts
Pants: relaxed fit jeans (not too baggy and not skinny), khaki pants, trousers
Jacket: blazers for different occasions (casual or dressy), definitely avoid hoodies unless they were purchased from a non-teen store (RW co. or Esprit). Leather jacket looks hot when pulled off correctly and paired with a dark wash jean with sunglasses (but some people look like they're trying too hard so bring a friend to help judge that look on you).
Accessories: Sunglasses, Belt, maybe a necklace but personally I think jewellery is generally best avoided
Fit is extremely important. If it's baggy, chances are you'll look like a high schooler. Whatever your size, it's best to choose something relaxed but fitted. That is, dress your size and if you don't know, ask a sales associate for help. If you dress your size, it'll compensate for whatever size insecurities you have. If you're smaller, it'll make you look more in proportion and if you're bigger, it'll trim you down.
In addition, if you look good underneath your clothes, your clothes will look better too.0
