That's right, because it is supposed to fit snug. But if you want a loose bangle style, then get the 17.I went through the same thing......I bought the 17 after FINALLY deciding on 17 rather than 16..........wore it for a week........and I felt that it was too big, and had too much movement on my wrist. So I called the store, and said I could exchange it for a 16. That's what I wear now. Anytime I see pictures of Celebs with the bracelet........it's pretty fitted! I think b/c you wear it 24/7.......you shouldn't feel it flipping around......did this make sense? JMO
You can go back to the store and try them on again... it's hard to deicide at home without the bracelet in front of you.
