What I do know is that I'm taking out the complexity and have decided to go with her active wear. Black tights. Black long sleeve crop top. Pink bra straps on display. And the red Russian athlete jacket.
The crop top I'll make.
The jacket I need to order (from here http://www.ezcosplay.com/yuri-on-ice-yuri-on-ice-plisetsky-yuri-cosplay-costume-only-coat.html#.WTTHWLvauUk since this is the only place I can find it)
And of course, to top it all off will be roller skates.
Where shall I be wearing this? I'm not sure. Conventions don't seem too happy about roller skating. So maybe I'll forgo the skates... nah, not going to happen. I guess I'm just going to have to find another gathering of cosplayers that is friendlier to the idea. Or I just cosplay while skating.
