As pretty as my guitar straps are, I'm with Benji myself, just gimme a plain strap for my cameras. I could see these being a nice gift for someone (possibly a lady?) into fashion and shooting.
The Levi's straps - they have some pretty nice designs, but most of theirs have that super-thick puffed-up leather thing going on, I like the soft get'm's personally.
For my guitars, I have some really cool brocade get'm straps, each carefully chosen for a specific guitar - and yes, they mate for life!
