I've chosen artifical/faux leather to sew my 'gladiator tutu'. There are rivets on Gwendolyn's skirt but I used dombed buttons because I couldn't find any rivets in the shops. I had to sew a crinoline and I've worn this under the artifical leather skirt.
My armour was made from fiberglass but I had so many problem with the wearing because of the fixing. The upper parts of the armour were sliding down...
I asked Aoime to cosplay Grizelda with me that is why we made our weapon together. ^^
Some of You asked me about my wings. If You'd like to follow my technique here's a mini tutorial below. :)
The feathers made of craft foam. I like this material because it can be transformed by heat.
First of all cut the drop shaped feathers and then hold each piece above a toaster (or You can use a heat gun too). When the feather gets warm pick on the two edges and pull softly. If You do it right there will appear the main spine on middle of the fake feather. Finally, glue them together and it will be reached a wing form. Keep in mind You should make a right side and a left side wing.
Good luck! :)
