Foxy, I can relate. I just bought a nice Samick with great action, Floyd Rose, Tobacco-burst body with ivory binding. Off Ebay.
It arrives. Plays great. But without trying it on for size...well it doesn't fit. The upper bout cuts into my right peck. If only it were a contoured body! ☹
So I pick up my Mustang...an old '65 slab body...which I hadn't played in a week. It feels like my favorite old jeans. Light. And the curve of that narrow slab fits me perfectly.
Maybe a 70s contoured Mustang body would be even more comfortable, but I doubt it could be much better....and now that I think of it, all the reissues have a thicker body than the earliest '60s Mustangs, don't they? So the contour may be necessary. But the thicker '65 reissue doesn't get a contour... 😕
