Naah, the male civilian suits dont impress me. They dont look like anything worn during the 24th century unless on a holodeck. So unless they add holosuits i wont be interested.
The female cocktail dresses on the other hand... I cant wait to se my science captain in one!
Holosuites are going to be tricky - they're going to need everything from the Battle of Britain (flight sim - awesome!) to the complete Sherlock Holmes stories to please the purists.
More realistic, thought, would be Vic's lounge as an alternative to Quark's bar - complete with a band, an' everthing!
It'd be the perfect place for these new outfits - if only because Vic's has a strict dress code!
