Get Fitted: Blouse or Top Sloper Instructions

Sloper Instructions It is essential to mark and sew accurately to get an acceptable fit. This is a procedure to get the sloper well fitted. Be cautious not to over fit. You are not a statue. Movement, posture, fatigue, rest, shoes and under garments can all impact the fit. The sloper pattern must at least equal your full circumference at the fullest part of your body. I recommend Connie Crawford blouse fitting pattern number 1201. It is available on her website: It comes in 2 groups of missy sizes and 2 groups of plus sizes that correspond to bra cup sizes. Choose the pattern that includes your size and your bra cup size. Another advantage is that it is not just a bodice but goes down to the hip level. Measure all the way around your body at the fullest part of your bust. Write this number down here: (a)________________ Measure across the front of your body across the fullest part of your bust from side seam to side seam. Write this number here: (b)__________ Divide this number by 2. Write this number here: (c)____________. Choose a pattern size that is equal to your side seam to side seam measurements across the fullest part of your bust. Measure the pattern pieces to determine the width across the bust. Write that number here: (d) _____________ On the pattern mark the seam line on the side seam at the bust line and measure from there to the center front line. This number is 1/2 of the distance across the front from side seam to side seam and should equal the number (c). (d) should equal (c). Now subtract (b) from (a). Write this number here (e) __________. This will be your back measurement. Divide this number by 2. Write that number here: (f)______________. Measure the back pattern piece at the line that corresponds to where you took the full body measurement. Write that number here (g)____________. This should equal (f). cut a center back seam as this will be needed in the fitting the upper back. If you have a very full bust or a muscular and wide back it is possible that you will need different sized front and back pieces. Please let me know and I will advise you regarding the armscye and sleeve. You will cut the larger armscye on the larger piece and the smaller armscye on the smaller piece. You will cut the sleeve corresponding to the size that you cut on each piece and blend the sleeve at the top of the sleeve cap. Sewing the muslin sloper The muslin must be sewn accurately to determine the fit. Press your muslin fabric prior to cutting. The next step is to mark all seamlines on your muslin pieces. Staystitch the neckline, shoulders and the armscyes. Stitch from the wide to the narrow so that you can cause minimum stretching of these seam lines. Press the staystitched muslin pieces. Then compare the neckline, shoulder and armscye with the pattern to determine if there is any distortion. If so correct it by steaming the piece back into shape or marking the correct seamline onto the pieces so it can be sewn accurately. After stitching the seams press them flat then open. Cut 2 inch seam allowances on the shoulders. Stitch these on the outside. You will be stitching wrong sides together at the shoulders. Cut one inch seam allowances on all other seams. If using Connie's pattern cut as shown on the pattern pieces. Set both sleeves as you would in a garment. Add a center front zipper. It is possible that you will need an upper back adjustment which is then made from the stitched muslin. This adjustment may require the assistance of a sewing friend. If the back neckline does not sit at the base of the neck slash 1 inch from neck seamline from center back to but not through the back armscye seam. The muslin fabric will spread the amount needed. Measure this at center back and over the shoulder blades. On the paper pattern make slashes every 1/4 inch and spread 1/8 to 1/4 inch until you have added the full amount needed from the muslin.
