This came extremely tangled. It took me about 20 minutes to untangle it then after I untangled it one of the pieces detached so it took me another 20 minutes to get it back together however, when I finally wore it, it was so cute but this should definitely be like on a cardboard body, so it won’t be so tangled up. I mean, it was ridiculous almost threw it away.

I made some Modifications to this as it is definitely not meant for taller and/or larger women. I would not purchase again but only for that reason- it’s a nice piece of jewelry
