Take an OTK boot like the SW 50/50 boots.  What is the style difference between the suede and leather versions?  Is one more sleek, boho, elegant, edgy, classic, dressy, rustic or whatever?  Or is it all in how you style it?  I am trying to decide which one to add to my boot collection (not necessarily the SWs but some fitted OTK boots) and I can't seem to figure out which would be more my style!

I did return the ones I'd bought earlier as they were a bit too slouchy at home.  And I have a pair of slouchy black OTK flat boots that are pretty casual. 

All input welcome!
