Imagine the bell of a trumpet facing toward the ground. That's the look of a trumpet skirt, a style that's subtle yet sexy. When you add triangular inserts around the bottom of a plain skirt, you increase the hemline and make the skirt move as you do. You can create a fun and flirty trumpet skirt by transforming a plain A-line skirt from your own closet. Choose a soft fabric that flows around your body, and add skirt inserts to match the skirt fabric or in different colors for a fun accent.
Place the insert fabric on the table in front of you with the right side, or brighter side, facing down. Draw four triangles on the fabric that are 6 inches wide at the base and 12 inches tall. Cut out all four triangles.
Turn the skirt inside out. Measure the side seam from the hem up 11 inches, using a measuring tape. Mark this point with a straight pin, and do this on both side seams. Open the seams with a pair of sharp scissors, snipping the threads that hold the seam together.
Fold the skirt in half so that one side seam sits directly on top of the other. This will help you find the exact center of the front and back skirt panels. Cut the front and back panels from the hem up 11 inches. You now have a skirt with four slits running up from the hem.
Fold up the bottom edge on each of the four fabric triangles, folding the edge toward the back side of the fabric. Make the folds 1/4 inch tall. Fold the fabric again on top of the first fold, folding another 1/4 inch. Pin this double-folded hem to hold it securely on each piece. Stitch the hems on each triangle.
Pin the triangles inside the open slits around the edge of the skirt bottom. Place the point of the triangle 1/2 inch above the top of the slit. Pin down each side of the triangle, connecting it to the sides of the slit. Make sure the bottom of the triangle is perfectly aligned with the skirt hem.
Sew the inserts into the skirt by stitching from the top of the triangle down toward the hem on one side, then going back to the top and sewing down toward the hem on the other side. Do this with the other three triangles.
