While the girls here will probably be able to help you fine-tune your skills, a quick look at your profile pics doesn't leave me with the impression that you have any problem in that area. I'm no fashion maven or anything, but your dress and overall appearance don't seem out of line at all.
It's fine to recognize an area of your life that you want to improve, and I have no doubt that you can. But know that you are FAR from being awkward and clueless in that area, and you don't need any real changes to be attractive. If you want to tweak things a bit, that's fine, go for it!
