Hi there! I just finished my Spider-Gwen for Wondercon. There were lots of lovely Gwens there who all did their suits in different ways. There are lots of great pictures
to show all the Gwens at a meet-up.
For my own amusement, I've also been compiling a resource list of all the tutorials, concept art, and step by step pictures I can get my hands on at my blog on tumblr
Best of luck, Gwen is a delight to cosplay!
