That LSU leo is a strappy back done well. By all means have the straps - they’re pretty, but line them (with non-flesh coloured fabric), and then they’re also flattering and practical.
No photo, as I'm watching on TV, But I am 99% sure GWU is wearing a navy blue velvet leo with white sheer sleeves. Rhinestones on bodice. It's very 1998.
Thanks for the pic. Was hard to really see with the quad view they used for the broadcast (and I was trying to make soup at the same time). So not sheer, just white lycra. Looks like maybe mystique where the rhinestones are, and then velvet bottom.
