Op, this is an anonymous forum, no one could guess you’ve had a crap year or this was the first thing you’d bought for fun. People were just responding on the skirt itself, no one could guess just how important it was to you. I also said it looked cheap on the model as it looked thin and Ill fitting on her and hoped it looked not like that in real life.
if you just wanted something nice to wear for Xmas, then this skirt fits the brief, but you also asked how to dress it down, which indicated you wanted more use out of it than just Xmas. If it’s just something pretty for Xmas, it’s perfect, and you’ve had lots of suggestions.
Honestly though, someone not liking the skirt and thinking it looks cheap etc isn’t a personal attack on you, they were just talking about a skirt with no context.
