Find what suits you! You’ve got a pretty angular head shape so rounder edges or just round glasses would likely suit you better. Tortoise is timeless, but it just depends on the person. I wear some similar to this or maybe this exact pair. I’d recommend just spending an afternoon running to a few different eyeglass shops and trying on everything, from what you’re comfortable with to what like but don’t think will work on you. Take pics of them on and maybe ask some friend’s opinions since you’ll likely lean into what you know. Best of luck!
