yeah, as a general rule the hierarchy is wrinkles < skin < clothing
once you get into clothing though it's still the wild west. Fabric and placement is just so important (and individual) - I spent around 10 years thinking the best size skinsuits were the one's it took 4 people and a stick of butter to get you into. (maybe even true with skinsuits ~5-10 years old) but now with the fabrics being textured or with specifically designed seams, too tight and you change the intended benefit of the suit (usually for the worse) so now I think "the right size" matters more than the tightest thing you can zip up.
Not exactly related, but another thing that I had always "assumed" / built a bias on was numbers being pinned/glued on tight so they didn't flop around. While that's probably a good rule of thumb, I had to rethink it when someone showed me their data of a (well placed) less form fitting number actually being a benefit.
Aerodynamics... so hard to get over our (often hammered in) notions of what works and why.
