Beautiful just like the the picture
Very cute 💕💕I probably should of gone a size up but it still fits fine.They're a lot better quality than I had expected, well put together and nice material. I wear a size 6.5 and got a 36 I'd suggest going up to 37/ a size above what would normally get.
It fits great and us nicely made
Exactly what I asked for, very stretchy and voluptuous.
So appreciated the support when something go lost in shipping! They made sure we got the items before prom!
Absolutely beautiful! And amazing support when there was a problem in shipping.
I went ahead and followed to the measurements although I was scared it would be too big for me or worst, too small... I was surprised seeing it in my door so soon, the delivery was quick I expected to see it in 25 days xD but it got here 12 days after order was placed.
APART from the unpleasant smell it came with... I ABSOLUTELY loved the bubble skirt... it fit RIGHT, not too tight and not too big, it is indeed mini and it complimented my figure more...! Honestly dont regret this purchase at all, worth the money as I'm preparing a concert fit !!😭😭 ITS SO CUTE
