Underwire Charts So sorry, I no longer maintain a page on underwire charts. They change too much! Please visit my Lingerie Resources page for ideas on where to buy wires. Stores selling them often publish printable charts of their wires.

I am full busted and would like to make my own plunge bras with narrow wires. Preferably a place with cheap shipping to the US? Reply Amy March 27, 2014 at 11:29 am (1 year ago) Ahh, I really need to update this page. As far as I know, there are only two online shops that offer narrow wires: Bra-makers Supply and Sewing Chest UK. The wires at Sewing Chest are heavy gauge and the strongest I have tried. I haven’t bought one of the Bra-makers “vertical wires”–the narrow ones–but the description suggests these are strong wires. Both of these shops also offer plunge wires, but many plunging wires are usually already narrow to begin with. The longer the tail is (at the side) the better support it will have for a larger cup. It’s also easy to just cut a narrow wire to the length you want. I don’t know if either shop offers cheap shipping, but I have found Sewing Chest to be very reasonable.

However, my breasts are very wide (because I am older much of my tissue seems to be under my arm), and have difficulty finding a an underwire bra that does not cut into the side of my breast. How can I determine wire size? Reply Leave a Reply Cancel reply Your email address will not be published.
