As far as I'm concerned, people with small face are easier to find a suitable glasses, for they look beautiful on various styles of glasses. In terms of your problem, I think you'd better choose small framed spectacles, for large framed eyeglasses would make their faces look smaller. What's more, they are suggested to choose rectangular specs which would make their faces look wider and more modeling. The most concrete suggestion is that try more glasses on you in solid shops to look for what kind of glasses fit you well. As long as you make proper matches, your requirements would no longer be a problem that is hard to solve.
