How To Make A One Piece Strapless Bra Slip

It's hard to find a slip to wear under a strapless bra but you can make your own with a few tips, instructions and supplies.

You might think that a particular strapless dress you're wearing doesn't need a slip under it but after stepping out into bright sunlight you could quickly change your mind. When wearing a strapless dress women are often faced with wearing a half slip or none at all since strapless slips are nearly impossible to find. Although making one is easy the style of dress you'll wear it under is a factor in how it should be made. A-line dresses require the design to be slightly different than a full-skirted ensemble.

Tricot is one of the easiest fabrics to work with when making bras and slips. It stretches where needed but isn't clingy. There are different designs of tricot. One is a thick material mainly used for making brassieres. Another is a light, flowing type suitable for slips and nightgowns. Use 3 to 4 yards of the latter for knee-length slips and 5 to 6 yards for floor-length. Since tricot often comes in extremely wide widths you might get by with even less yardage.

Write down the bust, waist and hip measurements along with a measurement from waist to floor, waist to mid-knee and waist to mid-thigh. Write down the hem measurement of a dress with which you'll be wearing the slip, from side seam to side seam. Since the pattern can be easily varied depending upon the outfit it's a good idea to draw the initial pattern out on paper then make adjustments for full-skirted, minis and other dresses for future sewing projects.

On paper draw the measurement for half of the front hem of a dress with which you'll be wearing the slip. It doesn't have to be the exact measurement since you will probably be wearing the slip with several different outfits. The piece of pattern paper will be placed on the fold of the tricot when ready. Mark the waist line on the paper and angle the paper from hem to waistline. Mark the bust line and angle the paper from waistline to bust. Cut this pattern piece then cut another for the back which will also go on the fold. The back pattern piece should have the same hem measurement as the front, then angle to the waist, then to the mid-back. The back width should be a little broader than the front and should be scooped slightly rather than cut straight across.

Mark the exact center of the front top piece. Cut the fabric to the pattern sizes then place the two pieces right side together. Seam one side. Hem the bottom or use lace for edging. Along the top edge fold the fabric over a half inch. Starting from the open side seam stitch in quarter-inch elastic gently across the back then around the front. As you're stitching the front stop at the exact center and lay down a small piece of quarter-inch elastic then continue stitching across it and the rest of the front. The elastic piece for the front center should be three inches long for size A and B cups, four inches for size C and D cups. Stretch the elastic and stitch it straight down the front center of the bust line.

Trim the top edge of the slip with lace if desired. Stitch the side seam shut. For more support in the bra sew in padded liners. The best way to do this is to try on the slip. Slide the liners in and pin into place. They should go from the small elastic piece over to the side, but not quite to the side seam.

Variations to the slip pattern can include straps that attach with velcro for wearing with spaghetti-strap dresses. The slip can also be made fitted from bust to waist then flared from waist to hem. Make floor-length, tea-length, knee-length and even mini slips with this same pattern.
