Baggy seat in pants

femme07 | Posted in Fitting on

I’m making dress pants for a size 4 client.  She wants the seat to be more fitted.  What’s the best way to adjust her seat?

    On my size 6 daughter, I need to use a size 2 or 4 back pattern and a size 8 front pattern. Using the smaller overall pattern in the back takes a lot of the extra volume out where she's very narrow, and the seat is much more proportional than if I just adjusted the crotch length and depth.

    Using different size patterns for front and back sometimes require a tweaking of the seams where they meet, but it's not a very big ajustment and isn't noticeable.

    I found the articles in Threads #s 122 and 128 very helpful in fitting pants through the crotch/seat.  It was an easy adjustment to the pattern that resulted in a great fitting pair of pants!

      Thank you so much for your responses.  I'll let you know how they turn out and what method worked for me.

    Depends on where she wants it fitted.

    Are you talking about the overall fit around the hips?
    Then take it in at the side seam.

    Are you talking about the pants being loose under the buttocks?
    You can shorten the back crotch curve and take in the back inseam accordingly. One thing I have started experimenting with recently is leaving the inseam open from crotch to knee then adjusting the back inseam/crotch curve in and out until you get the fit you want.

    I define a slacks cut as one that hangs straight down from the back of the hips. Tighter pants, such as jeans shorten the back crotch curve so the fabric fits in under the buttocks.

    If you take the crotch curve in too much, then the leg will buckle into the knee.

    Hope this helps.

    Have you ever sewn with Stretch and Sew patterns ? If not you should try one of their basic pants patterns, the original one was #700. Very old pattern but the instructions are fantastic for making a perfectly fitting pair of pants (mostly knit pants). The secret to their fit is measuring the person from her front waist area down and around the crotch and up to the back waist.  It tells how to make adjustments from several measurements.  Many women may be a size 10 but have completely different shapes. So, just measuring around hips doesn't always work. Some have bigger stomachs or rounder or flatter butts for instance thus the crotch around measurement is very revealing and important. Lets you know to adjust that seam curve in or out in either the pants front or back.

    Ann Parsons the originator has workbooks and patterns on her website if you can't find them in your local fabric store. 

    Hope this helps alittle. Oh yeah look at Palmer and Plesch patterns and books for Pants That Fit Anybody.

      What a great resource.  I've received so much good advice.  Thank you, everyone, for your help.  I will look for these patterns and I believe that it as the measuring that caused the problem.
