Fitting the Pants Block - Final Fitting

We've completed the initial fitting of the pants block.  Now we'll take a look at the pant after the initial adjustments have been made.

After marking the changes on your initial pant fitting, you'll re-stitch the pant along the marked lines.

In addition to marking the new seam lines and dart lines, please note that I also marked the waistline on the pant (below).


The pant looks much better already!

Now, mark any other changes you want to make, using a different color pen. I used red (see photos, below).

I really didn't feel this needed any more changes, so I just marked darts at the correct length (they weren't usually the same length on each side), evened out the waistline, and marked an "X" on the side of the pant that fit best.

Pin It

It's virtually impossible to pin each side of the pant exactly the same way.  Look closely at the pant on the form (or, ideally, on yourself), and mark the side that looks best.  When you take the pant apart, THAT is the side that you will copy for your block.

Take the pant apart along the stitch lines, cutting off ALL seam allowances.

I laid the new pant over the original paper pattern so you can see the changes more clearly.

The original pant had very straight sides and center back seam, to allow the pant to be pulled on without a zipper.  The pant was drawn in at the waist with a drawstring or elastic rather than shaped with darts and curved seams.

Pay special attention to the center back crotch seam.  The original is straight up from the curve, which is not typical of a fitted pant (again, this was meant to add fullness at the waist for ease of wear).  After pinching out the "dart" shape at that seam, the new shape is much more typical of a back crotch seam - angled away from the curve.  It fits much better over the buttocks that way!

You can also see that the side seams and the inseam have a bit of shape instead of the straight, boxy leg of the original.  It's still a fairly full leg, but there is some shape at the hip and inside the leg (to balance the adjustments to the outer leg seam).

The front pant didn't change nearly as much as the back.  The crotch curve of the front is fine; the front crotch seam SHOULD be straight up from the curve.  There is no angle or "dart" in the front.

The curves at the hip (outer seam) and thigh (inseam) match those of the back leg.

The front leg is not as wide as the back, but it wasn't on the original pattern, either.  A front leg should always be more narrow than the back.

This pant (the muslin version) can now be traced to cardstock and marked, as you did with the dress  block.

What's the Next Step?

You're ready to start designing pants!  Flared (or boot cut), tapered, shaped yokes - there are lots of options!

Step-by-Step: Making and Fitting Your Block

Need More Help with Fitting Issues?

The examples on this site reflect MY fitting issues and how I resolved them.  YOUR body is likely very different. 

But, since this is a site about MAKING patterns and not specifically about fitting, I'm not going to address other fit issues here. And believe me, there are others who can address this issue better than me.

Any of the online classes and books listed below will help you achieve good fit. You can use the techniques on any pattern; but why make the same corrections over an over again?  Apply the principles to your block, and the fit corrections YOU need will be automatically built in to every pattern you make!

I can recommend any of the following classes or books to help you achieve good fit, no matter what your size or shape.  I have taken some of the classes and own or have used almost all of the books on this list, and have been pleased with how they address fit problems.

I am an affiliate of both Amazon and Craftsy, so I do receive a small commission from the sale of any of the books or classes when you use the links below.  You can also go directly to Craftsy or Amazon to order without generating a commission.

Online Sewing Class

Craftsy offers online sewing classes, including classes that specialize in fit. Two that I'd look into include Easy Fitting the Palmer/Pletsch Way: Shirts & Tops and Sew the Perfect Fit. They also have a fabulous class in altering patterns to fit plus sizes, called Plus-Size Pattern Fitting & Design.
