Don’t ever go glasses shopping by yourself. It is HARD and you will fill up your photo stream and bankrupt yourself by sending dozens of MMS’s to anyone who can help. You will spend over an hour in your local Specsavers, trying on the same dozen pairs of glasses, over and over and over again. You will get very frustrated and start asking bewildered strangers “Does my face look too big for these frames?!”.
(Just FYI, I didn’t actually end up buying any of these styles!)
