I was trying to find something to fit my narrow face.  The only description regarding size was "unisex", so I took a chance on this.  They were decent looking sunglasses, but much too large for my face, but I found I could bend them to wrap tighter to my face, but was afraid to try to permanently bend them to this position.  So I emailed JiMarti customer service with 2 simple questions:  Is there a way to reshape them to fit my face better, or if not, do you sell models for narrower faces?  The first response from "Misty" said "since that was an Amazon order, we don't have any info on that.  Contact Amazon and they will hook you right up".  What?  So I responded to Misty asking if they aren't in fact able to answer questions about a specific model of THEIR OWN sunglasses, and repeated the questions in more simpler form.  Misty's next response was equally baffling and of no help:  "We can't custom fit sunglasses via email, that's why we offer a 30-day return policy."  I think she was named "Misty" because of the mist between her ears.  Hopefully she's not representative of the whole company, but either way, I will be returning these glasses and in my further searches will skip over any JiMarti brand sunglasses.  If you've got a big head,  you may like these.
