Those flowers really are pretty outrageous, even though floral patters are fashionable this year. But if you want something that will really grab attention under the stage lights, you need something more shiny. Like, a strap with sequins.
I have a strap that's outrageous in a different way. White leather, lots of rings, grommets... 0.99 pence on Ebay UK, seemed to be completely unused. Apparently somebody paid Levy's a lot of money for a custom order, got it, and went "oh, wait, this looks like I bought it in a sex shop" and never even attempted to put it on an instrument.
Here it is being outrageous in an iPhone mirror selfie.
And a few more of the grommets here.
