Underwire Sizing Kit - 3 Set Target Sizes

Flexible steel for support with comfort!

You will receive 1 pair of wires in your target size, plus the next size larger and the next size smaller, so you can really dial in your fit. Once you've finalized the size you need, you can mail back the other sizes, in good condition, and we will mail you your correct size in exchange.

Size 32 - 42 in the regular weight and size 44(12) - 64(32) in the firmer weight. 32 is the smallest, so if this is your target size, you will also receive size 34 and size 36. 64(32) is our largest, so customers who target this size will also receive 62(30) and 60(28). Please see our wires page for more information about ordering.

If you are an instructor or you sew for many people of all different sizes and you're looking for the sizing kit that has one pair of every size we carry, please email us!

When you choose quantity 1, you will receive a PAIR of wires.
