What size hoop are you? That is genuinely the whole question with hoops, and everyone already knows their answer the moment they see it in a mirror. One-inch classics disappear into any outfit and any workday. Go bigger and the hoops stop coming along and start doing the talking.
Ours run from small yellow and white gold pairs through two-tone and oval shapes to diamond-lined hoops that enter the room slightly before you do. Sizes are listed on every pair, and the honest millimeters-to-real-life translation is in the questions below.
One more thing: nobody has ever put on hoops and felt less interesting. That is not a guarantee. It is a pattern we have noticed.
