I wanted to share with you a pattern alteration to help achieve the best fit in boyshorts, in particular for the Silvena Boyshort pattern.  Do you ever find the back of the leg opening gaping at the bum? Perhaps you have a flatter bum or narrower hips than what the pattern is drafted for.  Below is a simple pattern alteration to shorten the width of the leg opening to get a smoother fit.

Problem: Gaping at the bum

Symptoms:

Excess fabric and looseness at the back leg opening

Solution: Shorten the width of the leg opening

Determine the excess amount and divide by two.  For this example, let’s use 1″ as the excess amount; divided in two and we have 1/2″. 
On the pattern piece, bring in the inseam at the leg opening 1/2″ on each side.  You can see the new inseam and leg opening lines below drawn in red.  Measure the new inseam length on each side to make sure the lengths match.  Adjust if necessary.

If you  are using a pattern with elastic or bands to finish the leg opening, you will need to shorten those lengths as well.

If you have any questions, or suggestions for other panty fitting tutorials, leave me a comment below.  Until next time, Happy Sewing.
