Bought a size 5 for my fianc.  She loves it & has skinny petite fingers & wears it in her middle finger. No problems there with her.  I bought the same ring for me in a 10 to wear on my middle finger & it was HUGE & not a size 10 when measured.  It ended up bending & distorting so badly that it broke on me. I am disappointed with mine, but happy with hers.
