Need to cover a bit of overindulgence yet look chic? This DIY waterfall jacket with a belt is the answer.

My simple pattern for a lady's casual summer jacket takes mere minutes. You’ll need to already know how to make a belt and sew bias tape if you want to professionally finish the armholes.

Let’s get started making a waterfall jacket.

Tools and materials:

  • 2 yards of stretchy fabric
  • Measuring tape
  • Ruler
  • Tailor’s chalk
  • Scissors
  • Sewing machine
Making the pattern for the waterfall jacket

1. Make the pattern

Fold your fabric in half and then in half again. When you want to sew a garment with a 360-degree flare, folding the fabric into quarters is the best way to do it.

Measuring down from the top fold along the folded edge that has both folds

Measure down from the top fold along the folded edge that has both folds to determine the length. In this tutorial, I’m marking it at 28 inches but you can make it shorter.

Marking the exact measurement in a quarter circle

Once you have that mark, mark that exact measurement in a quarter circle all the way back up to the top fold.

Cutting along the quarter circle marks

2. Make the collar and armholes

Unfold the first fold. You’ll have a semi-circle.

Marking along the fold from the right side

Mark along the fold from the right side to determine how long you want the collar to be. I’ve marked it at 15 inches because I want a dramatically draped collar. You can choose to make it the same size or a bit smaller depending on how you want the collar to fall or drape over. 

Measuring shoulder width

Measure your shoulder width. Divide by two to get the shoulder measurement for the waterfall jacket. Mark at the end of the collar line with a vertical mark. If you’re like me and it’s 14 inches, measure and mark 7 inches with a straight line.

Measuring and marking armhole depth

From that line, measure and mark the armhole depth towards the left side - about 7 to 8 inches. Draw a straight line.

Making a jacket

Mark the mid-point of that line. Then mark 1 inch above and 1 inch below that vertical line.

Oval shape that will be the armholes

Connect into an oval shape. These will be your armholes. You can always make them a bit larger by increasing the size. Just make sure they are equal at the top and bottom. 

Cutting the armholes

Pinch the center and cut with the scissors.

3. Finish the waterfall jacket

If your fabric doesn’t fray, you can leave the armholes as is as well as the hem. However, if you want a smooth, professional look, make bias tape for the armholes.

Jacket with belt

Lay the folded fabric with the cut ovals on top of a piece of folded fabric. Trace the oval shape. Pinch the center and cut the oval out. This way you get the exact measurement of your armhole.

Cutting out the bias tape

Trace your desired bias tape width around the oval. Cut out the bias tape. Attach your bias tape in the usual way. Hem the entire circle. If you have extra fabric, you can make a belt.
