Because if you read the thread, and this one, you see that using words to talk about this, people are using the same terminology but are talking about different things. For example, the whole "granny panty" nonsense - from people that don't want the skirts, and apparently don't know what a granny panty is so they refer to it as that. (In fact, all these discussions make me realize that a lot of straight men don't know anything about female undergarments or lady parts, LOL.)
I get your point, and in general I agree. At this point there is zero credibility, people just put up with it to get the remaining figures. But I do think asking for pics in this case was a good idea, so people could show exactly what it is they are looking for. In doing so, they have shown that different folks want different things, though - but most agree that Glimmer's current "skirt" isn't great, but then again I think there are a lot of us who think other females have been well done lately (Octavia, etc.) and don't think it's some terrible issue that every female has. Glimmer is markedly different than her prototype, though - and since she really has a jumpsuit-type outfit, the little skirt just doesn't make much sense.
