I think most day gamers are indeed into the high class kinda girls, career girls and the model type girls so dressing smart is definitely the way to go if you ask me. Doesn't mean you have to suit up every day but incorporate some mature dressing into your style. Also be sure to create your own style that suits you, don't care what other people think of you.
For myself, I wear a blazer almost every day. I combine it with a v-neck shirt, a button-up or a v-neck sweater on a pair of fitted jeans. Then I top it off with the right watch and sneakers (I have many) and a nice scarf in winter time. It suits my personality and I look smart. I also don't care what other people think of it, Many guys always ask why I'm so dressed up all the time, sometimes they even make fun of it. However, the girls (on school for example) literally compliment me everyday on how I'm dressed so well and how my watch or my shoes complete my outfit.
Take your time to find your own style and build upon/around it! I still adjust my style from time to time and I always will!
