Just noticed that Selei appears to have the mirror universe Federation uniform on. I get that it's a time travel mission but at the least I think that if the outfits are unlocked they should be available to all Fed and KDf. Personally I'd like to see all costumes available for all but I get why that's not viable.
Say the Sierra and Anteres come to mind. They're mainly Starfleet main (though you can get open versions) uniforms. 7 of 9 would be a bit hard to justify too unfortunately. I'm all for it don't get me wrong but I get why SOME wouldn't be allowed. But the mirror one's should be allowed.
