I read the reviews ahead of time and then ordered.  My opinion is:  the beading and craftsmanship are pretty and it is a pretty piece overall.  A few of the glass bead were scratched or showed glue marks but better than average.
I am quite overweight and can still wear it as far as width other reviewers are mentioning - I think the problem is...if you look at the pic of the model wearing it, that is how they made it to wear so no one can put it up around their neck like a choker but if you let it hang down like the model, it is plenty wide and you have enough tie string to do so.
The 2 problems I had and the reasons I returned it (even though it really is pretty) are:
1st - if you aren't wearing exactly the right top or dress, it looks quite odd to have the neckline of your top or dress above the top of the bib necklace (you can see this in the model pic but since its just a gray tank under, its fine).  There are few things it looks good with.
2nd - the back is a nice soft felt like material that clings to your outfit so as you move the necklace doesnt stay flat.  The edges bend or bunch up with your shirt and it ruins the look entirely.
Overall - I give only 2 stars even though it is quite pretty because of the practicality issues.  If you want it for an art piece, its great to look at -- but as a necklace, its complicated :-)
