After it heals, whatever fits and feels comfortable. Rings will be fine, labrets will work if the curl of you helix is wide enough for the base, if not try short barbells rather than labrets. You need the gauge you were pierced at, or smaller if you want it to shrink a little to a smaller size. If you don't know your size, ask your piercer. So you can use 16g if you were pierced there, or if you were pierced at 14g but decided that's too large for you. I do not recommend anything smaller than 18g, and 16 is a smarter size. Too small and jewelry can migrate, and it has a better chance of cutting the flesh if it's tugged or yanked accidentally.
