I have a drawer full of sunglasses. Most of them were bought in a shop with soft lighting and have never left the house since. Three pairs do all the work.
A big black cat-eye pair for the city, which makes me feel like I am in a film. A small round pair that fit under a hat. And a cheap sporty pair that I do not mind losing at the beach.
Try sunglasses on outside, at noon, facing the sun. Everything looks good under shop lights.
