This is a fitting pack for the Round Wires that we carry in our shop.
Unsure of your wire size? We suggest going with your recommended wire size and one size up and one size down in case your breast root is wider or narrower. You will receive a fitting pack of three consecutive wire sizes to help find your fit!
The Round Underwire is a standard wire that is used for a number of bra patterns. Compared to the Regular Classic Day Wire, it is 10mm longer at the center front and has a rounder shape at the underarm area with less splay.
Please note that if your had purchased these wires before 11/18/2021, they were referred to as the Long Classic Day Wires.
You can use the Round Underwire with the following bra patterns:
• Pin Up Girls Classic Bra Pattern
• Pin Up Girls Shelley Bra Pattern
• Ohhh Lulu Sews Cindy Bra
• Contour Atelier Chelsea Bra
There is no size standardization across underwire suppliers. The pattern maker can draft their bra pattern based on a particular wire supplier and there can be variances in the lengths of the round underwires offered across different suppliers. Before making any pattern, I would suggest always walking the underwire around the wire line to make sure there's enough wire play before cutting into your fabrics.
Made from premium 22 gauge wire.
