I was nervous about the fit for these gloves; I don't exactly have "delicate bone structure," but the material was very stretchy and still comfy!  I imagine it will fit most adults without problems.  These gloves fit me to just above my elbow, which I found hard to figure out while I was considering purchase.  Hope this is helpful!  They were wonderful for my brother's wedding.  I would mention- I noticed pilling on the fingertips a few hours in to the wedding- they probably aren't good for any kind of repeat wearing, unless you're a LOT more careful than I am!  But they are great for one night occasions, esp for the price!
