Pants pattern alteration

Alterations pants pattern for athletic or full ( aka heavy) thighs front side only.

Since a lot of women develop heavy front thighs due to sport activities like swimming, running etc. which cause the front pants legs to be too snug at the upper thighs.

 Adding wide to the front pants pattern can help to achieve a better fit.

 Measure your thighs at 2 inches below the crotch, next measure the pants pattern front and back at the same height 2 inches below the crotch the total width of your pattern must be your thighs width + 2-3 inches ( 5-7,5 cm)

For example, if your patternwidth is 1 inch short in width you can add that amount at the front pattern.
If your pants pattern has a crease line you can start from there , if your pattern doesn’t  have a crease line, draw one see step 1 at the diagram.

 

 

Draw a horizontal line at the front pattern, 1 inch below the crotch line from side seam to inner leg seam.
Measure the space between this new line till knee height and divide this in 2 and draw a horizontal line halfway.

Cut the front crease line from the waistline towards the knee and cut open the 3 new horizontal lines. See step 2

Add a piece of paper under the slashed pattern and spread the pattern parts like the example diagram see Step 3
Draw a new crease line from the knee up to the waist, add at both sides of the new crease line ½ inch at upper thigh .The side seams inner and outer leg are now spread for about 1/8 -1/4 inch. You can ease in those inches (1/8 till ¼ inch) so the front side seam fits the backside seam again.

If your front pattern needs more than 1 inch then I would suggest to use a larger size pattern because otherwise the space at inseam and side seam lines are increasing too much and easing in will not be possible anymore.

  2. Thank you Els!
    I have a different problem with pants – too much fulness in the backunder the seat to approximately the knee. How would you advise on making this alteration?

  3. Dang, MIss J wishes she kept up her sewing! MAking her own pants would probably be easier than finding a pair that fits her big ol’ thoighs!

  7. Els, thank you so much for putting this up here.
    Great tutorial, and yes, it applies to me. It’s those bike riding/swimming quadriceps. Your knowledge and willingness to publish it and share it here is much appreciated.

  9. Ok. Getting bookmarked. I’ve been meaning to man up and try this alteration for a very long time, but I haven’t had the guts to do it!

  10. Els .- thanks for explanations. It really is very interesting and instructive for the settlement of trousers. This technique also serves to arms? I suppose it does, right?. thanks. Hugs and see you soon, Paco

  11. Yes, I am familiar with this alteration as one with those type of thighs! The tutorial and pictures are clear and easy to follow as always. Thanks, Els!

  12. I know you’ve given us this explanation before, Els, but this version is very clear and will be easy to find when we need to refer to it. In addition to providing a little more front thigh room, the alteration also has the effect of slanting the center front seam just a bit, and figures with full thighs seem to need that slight angle for a smoother, more figure-skimming fit in front. Thanks for taking the time to post this!

  13. Interesting method. I’ve used the method of adding to the inseam, but this looks more “accurate.” Thanks

  14. Can you do a tutorial on how to make a simple toddler/infant pair of flaired/wide-legged pants….maybe with a ruffel on the hem????

    We don’t do a tutorial on demand, there are a lot of nice patterns for children like this one http://www.fabrichound.com/store/product_info.php?cPath=16_19_26&products_id=11
    Which could be helpful for your purpose. Good luck sewing a nice flared infant pants.
