<human>: Give me the gist of the text in a nutshell

So over the weekend I went to a local lake/campground/beach and was fishing, and while I was fishing a couple of attractive girls approached and sat down on the dam from which I was fishing. Now I wanted to go over and talk to them, however as the title states I wasn't entirely sure how to. Personally, I am a very quiet guy when out in public with people I don't know-but am a very confident and bold person with my friends at home/their places. Now I'm saying I am not confident, but I just don't know how to approach them in conversation. The next day the same thing happened.

So possibly could my appearance help to improve those chances? For both days I was wearing aviator-style shades and had on athletic shorts, a plain tee-shirt, and sandals. I am extremely dark complected for a white male if that helps for what colors would look best to impress. Also I'd like to know what would be the best way to start the conversation or what to talk about.
<bot>: Need help on how to approach girls at the lake/beach. What should I wear? I am generally  fishing when I am there as well.
