Definitely go up a size. The 6 was more like a 3

Quality and look wise, this is an absolutely beautiful jacket. I love everything about it. I rented this for my daughter to wear on her Communion day, but unfortunately it was WAY too small. She is 7 years old and a very consistent size 8. I ordered the 8 but it didn't even come close to fitting. I think I'd have to go up to a size 12 for this to work but sadly, it wouldn't be here in time for her to wear it. I highly recommending renting this but my recommendation would be go to up 2 sizes.

Gorgeous quality. Arrived with tags on. Cute fit. But runs really really small. Definitely size up.
