I wear a size 17, or 18 if I want a little more room. Funny you ask about metal choice! I like them all! Plain Gold because its the original, Pink gold because its so pretty and feminine, and white gold because it's understated and probably the most versatile. My indecision about gold color, as well as with diamonds or without, is probably the biggest reason I haven't purchased it yet. Most of my jewelry, including watch, is W/G or platinum. My Perlee clover bracelet is R/G, and I wear it on opposite wrist than watch. I also have some yellow gold, including a great Roberto Coin Dia Centos Florentine bracelet. So, I'm not sure which metal color would best compliment my current pieces. I need to decide on metal and which arm I will wear it on, before purchasing. I know it's a good problem to have, but still frustrating!:help:
