My husband and I are leaving for Vegas on Monday. I haven;t been in 15 years and that trip was with young kids. Staying at the Aria and going to see "O" but that's all we have planned. Was thinking of bringing jeans, sweaters,leather jacket, and pair of nice pants (not a dress girl). Will be there for NY but not planning on going anywhere but the strip. Do I need anything fancier or is it all just casual wear?
