Arrived fast! Good quality and very good communication :)
Very satisfied! I got this for prom and its also custom tailored to be smaller and it fits perfectly! Thanks for the free gift, also excellent customer service. My camera makes it look a bit darker than it is but it's blue 💙
Thai product fits me so well , im a size 7 1’2 so order a 38 . If you have wide feet or thick calves then this sint a product for you.
Dress is exactly as described in the writeup. The dress fit well. I would have liked it to have been a little bit longer. However, it just covers everything. I like the quality of the material.
Absolutely love these boots , fits perfect. I got a 7 1/2 in other words 38.

Its literally the cutest bag ever!!! The big size actually hold a lot of stuff also the shipping was really good! This store has soooo many cute stuff so for sure will be buying here again!
Absolutely stunning! The boning in the corset is surprisingly sturdy for the price, and it gives such a lovely silhouette. Perfect for the Victorian-Goth look I was going for. Shipping was faster than expected to London!
