This product is a pair of nylon-coated steel wires. The inner tips have a slight color so you can easily pair them up and tell inside from outside tip. These are long wires, so they will have a bit more rise in the center front, which gives you more coverage.
We have done our best to keep our wire sizing consistent with other retailers, but there is no standardization of wire sizes.
When ordering, choose your band size and cup in the chart below, and purchase the size wire listed. If you are not sure what size you should order, we suggest buying one size up and down. The changes between sizes is subtle, but getting the right wire is one of the best ways to ensure a comfortable bra.
