So, a few things. First, the reason I posted that is because, if it was in other regions why it was not in ours? Laura said that it was like that first but they removed it later when the 4 man was gone but that's not the case, the proof of that? If you go to the stream where they presented Blackram Supply Chain and E.Fleet Supply Chain for the first time in the west, before the game even launched in the west, when BSC was a 4 and 6 man dungeon, they showed the items that you could get from that same NPC and this is what you would get, soul shields, weapons and accs but not the outfit.

And this is what you could get in the asian version around the same time
So is not that we had it while the 4 man version of BSC was in use, we never had that outfit in the same system or it would be shown at that livestream, it was actually the last stream before the game went live. Also, they talked about the drops from the dungeon and they never mentioned the Red Pirate Princess so I really doubt it was ever there. In the stream where they presented Bloodshade Harbor they showed this briefly and there's no costume in the list of drops.
Second thing, I've read a lot of times people defending NC West in many topics saying "Oh, well, they don't make decisions, they don't have a say, they just implement what NCSoft tells them to put" but that's a lie and a very sad one, because, again, if you look in the old livestreams, when they took questions from the chat, they repeatedly say that they didn't want to put things in our version that Korea or Taiwan had in theirs, for example, legendary weapons. Maybe people don't remember this, but legendary weapons were obtainable via Hongmoon Store in the asian version and NC West didn't like that so they were very firm in the decision to make it an item that everyone could get by playing normally. They also didn't like certain outfit decisions made in the asian version so they asked for changes to the dev team and I leave you proof of everything here, livestream titled "Blade & Soul Weekly Livestream: Unchained Update - February 18, 2016" https://www.youtube.com/watch?v=qcmy2Ec3FSM
Quote 23:00
"We asked to the dev team that the outfit was a little bit inconsistent, so the male version of this one originally had, you know, the cool pants and everything else, the lyn female actually had the pants and everything else but the other females had this dress that was beautiful, it's a lovely dress, but it felt a little bit inconsistent, specially since the lyn female had this particular outfit. So we asked the dev team if they could possibly either create a male version and a lyn version of the female outfit or a female version of the male outfit and so they created this particular version of the costume to drop in the instance."
Quote 43:30
"if you've seen it in other regions chances are we will, it like almost 99.9 percent chance that we will have it. The exception would be if it's related to business model, because our business model is custom, so, like, legendary weapons being on the store or legendary weapons being on a RNG box or legendary weapons, I think, in general are not available in our client right now. And so if they're related to business model stuff, you know, we make the decision in whether it's going to be in or not. Content related stuff, like pets, wings, stuff like that that you see in other regions we will likely get them in some point too, we just don't know when because that stuff is things that are kind of nice to have but are not necesarily tied to a particular content piece."
So, according to they themselves, they actually have a say in the things that they put in the store, so is not like they're mere victims of NC Soft greed. And they also have a say in the costumes that are put in the game. And maybe this is not an "important" topic but is one of the many things that you can take as evidence of the little care that the west team have nowdays compared to the old days. Yes, this outfit was not there from the begining, but they used to actually listen and stand up for the west players, now they barely answer a post.
