Satisfied
Color: Gold, Style: V
Absolutely love! My daughter does not want to take it off now. I can say it is a little long though for her she is 3 years old. I would recommend getting this for kids ages 5+

Pretty little gift for a child.
Color: Gold, Style: A., Color: Gold, Style: A.
Got this as a gift for my 9 year old daughter so I'm not sure if she'll really like or not until Christmas Day. It is very pretty though and I feel it suits her. It's not at all expensive, after all this is for a child. So crossing my fingers she'll like this on Christmas day.
