We dressed up and were ready to go. Turning heads on Fremont Street and getting tons of compliments for the sequin outfit, from everyone - even the doorman. While we were getting carded another doorman suddenly denied us access due to my "costume". I was wearing a sequin bomber jacket with sequin pants.
This place does have a dress code saying no overly baggy pants. I was wearing a one-of couture outfit that kinda was sporty, but still appropriate and VERY "Vegas". This wasn't baggy pants or shorts and a tanktop. This was designer-wear at it's best.
I respect rules, but you do need wiggle room in todays fashion scene (unless you just want a party full of people in badly fitted suits).
I personally wouldn't want to go again.
