This artist really enjoys Eva McKenna's uniform. This is now the second T-doll they've drawn wearing it.

Edit: And just now tagged the cosplay for Dasha, too (post #10841012). Seems they have a thing for the C&C advisors.

Edit 2: Looked back over the RE3 wiki and I was mistaken: this isn't Eva, it's Lissette Hanley. Correcting tags.
