How To: Underline a Lace Knit Top

Recently, my daughter needed a pretty lace top for her small, casual wedding.  After looking EVERYWHERE, even online and ordering only to be hugely disappointed in the quality, I started looking online for fabric, but then she found this pretty lace with a bit of lengthwise ‘give’ at her local JoAnn’s Fabric Store.  A ‘dive’ into my Cream/White Box of knit fabric scraps yielded the perfect creamy knit for a lining and just enough (not an inch to spare!).  Here are the details on how I created the ‘modesty’ underlining for her very special lace top.

Step 1:  Decide how high up the ‘modesty’ lining will extend on Front and Back

After cutting excess fabric from one side, use it as a template to cut the other side down the same amount.

Knit Fusible Stay Tape along the wrong side of the uppermost edge on Front AND Back provides needed stabilization BEFORE turning and stitching.

A zig zag stitch of 3 long and 2.5 wide 'finishes' the modesty lining upper edge.

I actually attached the modesty lining to the lace all across the Back with a zig zag, and also from the side seams to highest point of the curve above each bust on the Front, leaving the inward curve and lowermost point of the modesty lining hang free from the lace.

Step 4:  Continue Top Construction  With the upper edges of the modesty lining finalized and sewn, construction could continue for the side seams and sleeve insertion.  The finished upper edge of this modesty lining just barely goes above the lowermost curve of the armhole.

Step 5:  Finish the Neckline Since the finish she desired was a ‘bound’ look with the cream solid fabric, it was easy to ‘see’ at a fitting how it would look, as the cut edge of the lace top would actually be the uppermost edge once the binding was finished.


I cut the binding a healthy 2" wide, with the greatest stretch going the length of the binding.  I cut it 10" less long, allowing for a 1/2" seam that was placed at the center back of the neckline.

The photo above shows the 3/8″ seam allowance from stitching the right side of the binding to the right side of the lace neckline edge.  Making sure both layers of the seam allowance were tightly wrapped was important as I snuggly wrapped and pinned the binding around to the inside of the neckline.


Carefully stitch 'in the ditch' from the garment right side.

VERY VERY carefully trim the excess binding from the wrong side very close to the stitching.

Sleeve hemlines were bound in a similar fashion.

Step 6:  Hemline Finishes The top lower body hemline was stitched with a zig zag, handling both fabrics as one.  Shirring each side up to the waist level using 1/8″ narrow elastic pulled to its fullest extent and zigzagged to the side seam created a flattering, curved hemline.
