Ok, so I had some time this morning, and considering my uber-Trek geekness, I actually decided to do a little research on Seven's "catsuit." What did she wear most often?
Here goes:
Seven had two different suit versions, both of which came in multiple colors. There’s a high-collar version (which came in silver and brown, and disappeared quickly), and a low-collar version (which came in brown, wine, blue, and blue with gray sleeves, and stayed around most of the time).
Season 4: Seven appears in her “catsuit” in 21 episodes. The trend is the silver high-collar suit for her first few appearances, followed by a brown version of the same suit for one episode. After that, it’s the brown low-collar version for the rest of the season.
Silver high-collar appearances: 3
Notable episodes: “The Gift:” First reveal ‘de-Borgified’
Brown high-collar appearances: 1
Brown low-collar appearances: 14
Notable episodes: “The Raven,” where she finds her parents’ crashed ship
Season 5: Seven appears in her “catsuit” in all 26 episodes, including, for the first time, one episode where she switches suits toward the end (“Infinite Regress”). She starts out in the same brown low-cut suit she wore through most of season 4, but then alternates with her blue low-cut suit with gray sleeves. Eventually she ditches the brown version and replaces it with a wine-colored version, and continues to alternate the wine and blue versions for a while, then switches completely to the wine version for the latter part of the season.
Brown low-collar appearances: 7
Notable episodes: “Drone,” where she meets a 29th Century Borg drone
Blue low collar w/gray sleeves appearances: 10
Wine low-collar appearances: 10
Notable episodes: “Dark Frontier, parts 1 & 2,” where we learned more about her past and see the Borg Queen on Voyager for the first time; “Someone to Watch Over Me,” where she explores dating; “Relativity,” where she’s sent time-jumping through Voyager’s history
Season 6: Seven appears in her “catsuit” in 25 of 26 episodes (as far as I can tell, she didn’t appear in “Muse” at all). She mostly appears in the wine-colored low-collar suit she began to wear in Season 5, although the brown suit makes a few appearances. She also wears an all-blue suit for the first time, but not very often. In fact, there’s only two episodes where she wears it for the whole episode, and she had small roles; twice, she changed into it for the last scene (“One Small Step” and “Collective”; and once, she actually changed TWICE, from brown, to wine, to blue (“The Haunting of Deck Twelve”)! I wonder if it was particularly uncomfortable…
Brown low-collar appearances: 5
Notable episodes: “Unimatrix Zero, part 1,” where we again meet the Borg and Janeway, Tuvok, and Torres are assimilated
Wine low-collar appearances: 19
Notable episodes: “Collective,” where the Borg kids join the show
Blue low-collar appearances: 5
Notable episodes: “Collective,” where the Borg kids join the show (but only at the very end)
Season 7 : Seven appears in her “catsuit” in 23 of 26 episodes (She only appears as a full Borg in “Shattered,” and only in civilian clothes in “Workforce, parts 1 & 2” aside from a tiny clip where I couldn’t tell what she’s wearing). She follows the same pattern as in season 6, mostly wearing the wine low-collar suit, while sometimes changing it up with the blue and brown versions.
Brown low-collar appearances: 5
Notable episodes: “Unimatrix Zero, part 2”
Wine low-collar appearances: 13
Notable episodes: “Endgame,” The last episode
Blue low-collar appearances: 6
Series Totals:
Silver high-collar suit: 3 episodes
Brown high-collar suit: 1 episode
Brown low-collar suit: 31 episodes
Blue low-collar suit, with gray sleeves: 10 episodes
Wine low-collar suit: 42 episodes
Blue low-collar suit: 11 episodes
Anyway, to my mind, you can think about it a few ways. If you want what she showed up in first, and what’s most common in toys/statues/promotional materials, it’s the silver suit. If you want what she wore most, it’s the wine suit. To me it’s between those two logically, but I do have a soft spot for that blue suit with the gray sleeves myself!
