Sunnies are a hard one to buy on the internet because everyone's face shape is different. I made sure to measure out the frame size on measuring tape and hold it against my face to see whether they'd be too big/small for me or not. Another idea is to cut out the dimensions on a piece of paper (which I also did) and see if the shape/fit/size suits you. Got the shades in black, I loved them so much! They fitted perfectly and were true to size/measurements were correct. One thing I did not like too much about them was the fact that there is no bling/brand name on the sides. It's just plain, which really sucks because I have not spent more than this before on a pair of sunnies and to the untrained eye they may look like they're not as expensive as they are :(. I'm not saying they are shabby though! They are definitely VERY good quality, you can tell by the feel and look up close, The case they come in is so cute! Like a coin purse, made from leather, lined with blue velvet! LOVE!
