I don't think I've seen any military dresses onsite but it would be nice to have some like any of these 1 2 3 4
I don't think I get what's "military style" about them, but I would use something styled like the first one. I'm about 13 years past the age I last held any interest in the gothy looking ones, personally, so I would hope they come in real colors.
That could look so great ^_^ Support!
The was/is pretty popular as a custom, and while its not like the examples shown (neither am I suggesting subeta makes a similar version to this), it shows how cute a dress along these lines can be :D
