How to Sew a Girl’s Seaside Sundress

Our favorite time of year is upon us! Living in the south, there is no time of year more beautiful than spring. The trees and flowers are blooming, days are getting longer and temperatures are on the rise. One great thing about warmer temperatures is that it is time to break out the sundresses! Our girls live in sundresses this time of year. We love sewing sundresses because they can be completed so quickly compared to a winter garment. They are also perfect for showing off all those bright cheerful fabrics that you have been hoarding all winter.

For a professional look finish the seams with a serger or trim off ½ of the seam allowance and finish with a zig zag stitch. Iron the seams flat and set aside.

Topstitch on the right side of the fabric right below the seam.  Hem the bottom raw edge of the dress.  Turn the bottom raw edge up ¼” and iron flat. Turn up another ½” and iron flat.

10. Pin the straps to the dress  With the dress wrong side out, find the center point of the dress front and mark with a pin. Measure over 5″ in each direction from the center point and pin the straps to the dress. The straps should be place so the finished raw end of the strap extends ¼” past the bottom fold of the top elastic casing on the dress. Repeat for the dress back and remaining two straps.

  1. Glad to see that you fixed the fabric measurements for the larger top. This should be called a top because it is not long enough for a dress. The finished product is very cute!
