To make a tube dress, cut a large rectangle out of a stretchy fabric. Fold the fabric in half with the right sides facing inward, and sew along the raw edge. Fold the top and bottom edges inward, and sew around the circumference of the tube to create hems.
- Select a fabric
Choose a fabric that has a medium level of stretch. Avoid fabrics that have too much stretch, as they could cause your dress to be too loose. Ensure that your fabric is not sheer when it is stretched to its limit.
- Cut the fabric
Measure your body from your underarms to the desired hem length, and add 2 inches; this is your dress length. Measure around your body where you want the top of the dress to sit. Subtract 2 inches from this measurement to get the width of the dress. Cut a rectangle in your fabric using the length and width.
- Sew and hem the dress
Fold the rectangle in half lengthwise with the right sides facing in. Using a sewing machine, sew along the raw edges with a 5/8-inch seam allowance.
- Adjust the fit
Flip the tube inside out, and try it on to test the fit. If it is too loose, sew a second seam with a larger allowance. If it is too tight, rip out the first seam, and sew another seam with a smaller allowance. If your bust, waist and hip measurements are dramatically different, make seams that angle in from the top and bottom of the dress to create a tighter fit.
- Hem the dress
Fold 1 inch of the top edge toward the inside of the dress, and sew into place. Do the same for the bottom edge.
