Though the beauty of making a garment for yourself is that you can make it to fit you exactly, there are certainly still reasons you may want to make a garment adjustable. The Tropo Camisole is designed to have straps of a set length, sewn from fold-over elastic (FOE), but whether you’re sewing for a friend who can’t try on the camisole, know that your body will be changing size (remember that the Tropo Camisole has a nursing option!), don’t want to have to worry about the elastic stretching out over time, or just like the lingerie-inspired look, adjustable straps are a great option!
To change your Tropo Camisole straps into lingerie-inspired adjustable straps you will need more fold-over elastic (FOE), 2 rings, and 2 sliders. You want your rings and sliders to be sized so that the FOE fits nicely in them when it is folded in half. In this example I used 1″ FOE and 1/2″ sliders and 3/8″ rings. (Read more about FOE sizing here). You will need a longer length of FOE, but the exact amount depends on how long you make the adjustable overlap on your straps. For reference, I added about 6″ extra per strap for the adjustable straps.
Start by sewing the FOE on the front and back neckline of your camisole (as you would before sewing standard straps as well).
Sew a strap onto the armhole. (Note: You can put the ring and slider on either the front or back. In this example I put them on the front, so if you want them on the back, switch “back” for “front” in the instructions). Starting with the front, extend the elastic a ways past the top front underarm, continue the elastic around the full underarm, and allow the rest to trail off the top back underarm. (You’ll want to attach the elastic in two steps like in the pattern instructions).
Thread the front strap through your rings from front to back and then fold the elastic to the back. Stitch the strap down under the ring and cut of the excess strap.
Thread your back elastic though your slider and then put it through the ring from front to back.
Take your elastic and thread it through the inside of the upper slider (from back to front) and then down through lower slider (from front to back).
Wiggle your interior elastic loop so that it is flush against the slider and then sew the end of the elastic to itself so that you are creating a small loop. Pull the outer elastic loop down and you’re good to go!
