During my 20's I always dressed in button downs with the sleeves rolled, slim fit chinos, and loafers. It did get me a lot of female attention because most dudes that age only own jeans and t-shirts. The downside was I also had gay dudes try and flirt with me all the time. Once I was with my now wife for a few years, I just switched to wearing v-necks and more casual pants. Now I'm a work from home dad and wear t-shirts and gym shorts about 95% of the time.
