On one hand - If someone dresses in a three piece suit everywhere they go, they come off as an incompetent soyboy with soft hands who can't do anything for themselves. On the other - If you're single, you should dress as if you might run into the girl of your dreams at any moment. So you have to stay between the lines. Dress like you're capable of doing work and not afraid of getting dirty. While at the same time, dressing well enough to attract a good woman. So, never wear trackpants or sweats unless going to or from the gym. Never wear dress shirts and dress pants unless attending a wedding or funeral.
