The costume itself is fine, not too terrible in terms of comfort and fit, but my big complaint is that the skirt drops gold glitter EVERYWHERE. It was such a nightmare that I couldn't leave my kitchen to look in the mirror when I tried it on, and I'm second guessing whether it'd even be appropriate to wear to a house party for the same reason.
The crown is also a bit cheesy looking so I think I'll leave that accessory at home if I can't find something else. Also, although it is meant to be a full length ball gown, the medium could be a bit shorter. Even with heels, I'll need to put some tucks in to avoid stepping on it throughout the day.
