The fabric is way softer than I expected! My daughter says it feels like wearing pajamas. Perfect for trick-or-treating all night.

My daughter can’t stop talking about how much she loves it — she’s already planned her accessories weeks ahead! Fits true to size and looks even better in person
Ordered a size 6 and it fits my daughter perfectly — not too tight, not too loose. She’s obsessed and keeps twirling in it every day before Halloween!
