Most Helpful Girl
It could go either way, to be honest. I find that a lot of the time, the more you get to know someone, a person with average looks who you were initially only mildly interested in can become someone you find attractive and extremely interesting over time. Then again, some things are impossible to get over.
My advice would be not to commit right away. In today's dating scene, immediate commitment isn't even necessary. Ask her out for coffee or lunch, go on a couple of dates, but don't jump into a relationship or ask her to be your girlfriend right off the bat. The "dating" part is like testing the waters, deciding whether or not you want to take it further and start a relationship or whether you're just not feeling it and think you're incompatible. Spend some more time with her and see if your attraction increases at all. If not - well, you can't really help that.
