I'm looking at this one for my daughter's birthday. She turns 20 next month and is asking for it. She's super tiny so I'm thinking it will be too big for her. She is 5' 4", barely 100 pounds and a size 0. She has the tiniest frame. She does like chunky jewelry tho but I don't want this thing just falling off. Anyone have this that could measure it for me?? Thanks in advance!
