It's the little details about a frame design that get me. Take this brand spanking new, just arrived from market, Masunaga frame. It is basically a large rectangular frame with fairly straight lines on the top, bottom, and sides, but the shape of the lenses within the frame are more rounded than the sides lead on. I just details like that.
I am wearing the matte havana. Shop in and the dark blue, which is great for evening or dress wear.
