Ohai.
I usually get some questions about what adjustments I made so I thought I'd post some photos of my FBA* for the Sewaholic Thurlow shorts
(* FULL BOOTY ADJUSTMENT)
I'm not sure who might find this useful, since I don't know anyone else with quite the rear differential that I have (15" increase from waist to butt apex), although the very helpful Kathy of kathy-sews is a slimmer version. I often find her pants adjustment details really helpful. Maybe someone out there will find my adjustments helpful as well!
I did a standard muslin process to get the adjustments, and then altered in my final version a couple of times before calling them "good enough." I have learned the hard way to transfer each alteration to my pattern BEFORE going on with any other sewing. I have a couple of other pants made where the final fit alterations are lost because I skipped that part.
I struggle a lot with motivation when fitting - I have lots of despair, having to do things over & over again. Ripping out seams, and the pin, baste, try on, tweak & finally sew together gets really old. However, wearing ill-fitting pants is even more annoying. If I struggle when sewing and want to just be done, I go try on some off the rack pants, have a good hard look at my booty in the mirror and give myself a serious talking too. I try to channel my late father, whose mantra was "If you're going to do a half-assed job you might as well not do it at all." (pun intended)
