DH wears lounge pants and PJ bottems around the house after his 10 hour shifts. Riley is his favorite character from Buffy the vampire Slayer and there's a scene where he needs some clothing assistance from Xander. Xander tells him "You need some fightin' pants? I can get you some fightin' pants." And brings him the most flamboyant 80s parachute type pants even. Long story short, we call his lounging pants his fightin' pants.
On a last minute Christmas shopping trip to Joanns, I found their Star Trek flannel. I hadn't made anything for my darling husband besides the winging it first attempts at things, so I thought "what a great gift, some Star Trek fightin' pants." I had a thrift store pattern, two yards of Star Trek Enterprise D flannel. I also had a bad bout of back/shoulder issues, so the present ended up being the components wrapped in a remnent of some old school baby wale with flamboyant colors, much like the named Fightin' Pants from Buffy.
I finally (after a few trips to the chiropractor) felt up to making the pants. Coincidentally, it happened to be about a week before Valentines Day. Two holidays in one fell swoop!!
After minor modifications to the pattern (I added pockets) viola, the final product.
and the aforementioned modified pocket. They ended up a little low on the thigh, but he's good with it.
