8.5 means kinda large, because i bought a leather bangle and had to sell it because it didnt fit over my hand, and my hands arent huge.. and 8.5 def would have fit over my hand if that was standard size
Eight inches in legnth is the standard size for regular ladies bracelets (ie ones that have a clasp)
Since the bangles dont have a clasp they have to be a bit larger for them to fit over your hand........
Personally I have tiny wrists so I have to go with the wider bangles that Coach makes. (1 inch width) I have several bangles but the 1 and a half inch one fits me best due to the width of it helping to offset the diameter of it.
I wish that they made different sizes of the bangles like they do rings. *sigh* (I have very small fingers too) Coach should make bangles that are one size smaller and one size larger in addition to their current (standard) size would cover everyones size needs. S, M and L!
