We stock 15 sizes of underwires, #30-#58.  Our metal bra underwires are made from premium gauge metal, to resist twisting.  The ends are finished with rubber tips, which are also color coded by size.  These underwires are classified as “regular length.”  The tip with the color is the side that should be on the inside, closest to center front.

Full Bust:  Measure around your chest evenly at the fullest part of your bust with your arms down.  Make sure the measuring tape is level across your chest, parallel to the floor.

Underbust:  Measure around your ribcage just beneath your breasts with your arms down. Pull the measuring tape somewhat taut.

To find your underwire size, subtract your underbust measurement from your full bust measurement.  Use that number along with your underbust size to find your suggested underwire size!  If you’re new to bra making and aren’t sure which size will work for you, you may want to also order the next size up and/or down.

For example, if your full bust is 40” and your underbust is 34”, the difference would be 6”.  Looking under the 6” column and across the 34” row, your underwire size would be #44.
