EDIT: Original review was written after trying on 3 necklaces, I've now worn about half the set and I think the issue is that they're different sizes. Some of them seem perfectly fine and a normal fit. The ones with the flowers seem especially smaller. The ones with the beading seem much bigger. Adding another star because the set is really an amazing value for what you get.I ordered the '24 pieces Set 1'. I'm an adult with a normal neck size and this set seems small. The string itself is not stretchy, the necklace relies solely on the weaving to expand. Once I manage to finagle it carefully over my head they fit, but snugly. They fit my 2 yo properly. Still very cute and an amazing value.
