DIY infinity dress

Sew an infinity dress

Cut out your skirt 

Start by folding your fabric into four and then using the measurement you took from earlier and marking it as your waist radius. After that, use the measuring tape again to find and mark your desired skirt length. Do this across the whole bottom, connect the strokes into one continuous line and cut out your skirt. Cut open one side of the skirt to form an opening.

Cut out your fabrics 

Measure out your waistband (three inches), mark it, and cut it out. Then, cut the waistband in half to have two separate pieces. Remember to leave a seam allowance and iron interfacing to one of the pieces. Next, measure and cut out your straps (I made mine twenty inches wide by sixty inches long, but I recommended making it a little bit longer). Fold them over and sew the edges, leaving only the short end open.

Attach the waistband 

Find the middle part of the skirt and the middle part of the waistband and make small snips in both. Next, sandwich the skirt in between the waistband pieces and pin them in place. (Pin along the entire waistband). Sew the waistband in place using a zigzag stitch and then make small notches in the fabric to help it lay flat. Iron flat. Find the middle of the waistband again and snip it.

Add the straps 

Divide the waistband into four, starting from the middle so that you have an even amount of marks on both sides (for me, each area was about seven inches). Have a half-inch overlap in the middle because the straps will be sewn down overlapping. Place the straps in place. Mark off the center of the area (for me it was the 3.5-inch point) and fold the center of your straplike a dart. Sew it down. Once that’s done, close the waistband. Fold the edge inwards on both sides and pin it up. Sew to secure, adding a top stitch on the lower side of the waistband.

Finish the dress

Fold the dress in half, divide your waist measurement in half and mark off that length. Mark off any leftover fabric with a straight line. Add another mark about eight inches down from there for the zipper and then sew from the eight-inch markdown. Iron the seam open when you’re done. To finish sew in your zipper. I forgot to add interfacing earlier so there is a little bit of tension by my zipper, but that can be easily avoided with a little iron-on interfacing. Finish the seam allowance with a zigzag stitch and then hem the skirt using a rolled hem. Do this across the entire raw edge of the bottom! 

I could not be happier with how this infinity dress tutorial turned out. It was fun to make, not too complicated and the results are more than worth it! Make this dress your own by playing around with different lengths and colors!
