No, this post is not about the shape or dyeing of said costume. Its about the texture.
This is how it was advertised. Ingame graphic by the way.
This is how it actually looks released. The whole skirt of the released version is plain white and undyeable. So there is no way to get the advertised look. To me this is clearly a graphic bug. As this costume is not just some free giveaway (it costs 2000 crowns) a fix is mandatory in my humble opinion. Please proof your integrity and give us what was advertised.
