There are so many name brands for your selection, such as, Gucci, Prada, Timberland, Kenneth Cole. Personally I would say Dior or D&G, but they are too expensive. I think it's unnecessary to spend too much on those name brand. I recommend Firmoo.com which offers many styish sunglasses with high quality, but they are much cheaper. If you don't have too much money to spend, just take my advice into consideration.
I can see that you are a guy looking for a pair of sunglasses that would be suitable for you. So, as a man myself, I would prefer Ray Ban sunglasses ,which is an American sunglasses brand. It has been renowned for its nice sunglasses for men and their design is original and cool. Also, they represent masculine sense and quality is prime. Just take a look at it.
