I got my Sammys in a 24 for a snug, fitted fit...I have tried 25s before and basically they were loose...they basically looked like I was wearing intentionally looser jeans...the only problem was that the waist was just too big, I could take them off without unbuttoning or unzipping them! In the 24s, since the waistband is so thick, I have to give it a little tug to get over my butt.
And I have NO butt at ALL and VERY tiny thighs...they have been a problem with many jeans for me before (especially Joe's)...so I need Seven A pockets or TR Joeys or R+R Roths to fit my thighs and butt. I posted pictures of me in my Sammys though, and I can tell you that the 24s are pretty snug in the thigh for me...my butt is just a lost cause
I didn't look at your measurements too closely...how do the Sammys measure up to your average jeans? I haven't seen how much mine shrink (haven't been through the dryer yet) but IMO Sammys look fine a little bit loose...as someone mentioned before, when they were skintight on JLO she looked awwwful.
