I purchased 2 high quality bridal underskirts for my wedding. I didn't end up using either of them. Both brand new. One is a tulle A line petticoat with one hoop optional at the bottom. The other is a fuller long tailed and layered petticoat for an A-Line gown, with 4 hoops. Although, the circumference of this one was too big for my gown, so I think it would be better suited for a ballgown.
I am 5'8" and both were the perfect length for me. Would need altered if you are 5'5" and under.
Both were purchased from seller/store MKMODAATELIERTR through Etsy. They cost $102 and $110, plus $80 shipping to Canada.
