And in college when money was scarce, this is what I had:
On the topic of cleaning off makeup, I found the liquid foundation was better at removing makeup than an eye makeup remover product, and the foundation costs less. Now, I use a microfiber face cloth with water. I have no special face soap. Plus I have tweezers, little scissors, a pencil sharpener, and I keep the chap stick in my purse or coat pocket.
I didn't date much in college either.
I am not going to say that you can look fabulous without spending a lot on makeup. But you can be well groomed.
