I really can’t tell if they are nude or not. If you say they are I believe you, but they could just be wearing skimpy outfits.
When I had Nikon cameras I used their straps for years. They worked fine. When I switched to a Canon R6 I bought a Peak design neck strap and I really liked it. I don’t think the Canon strap included is bad, just not as good. It has no quick detachment and it wasn’t as wide.
Who are you getting the promotion from? TFS? You could always just ask them.
