I need help locating the dress for Veronica, ive herd it was in the White Glove Society Suites, but i looked all over and found nothing, can anyone help ?

I got mine when I actually joined the Society during the Beyond the Beef quest. Other than that, only thing I can think of is killing one of the workers. Try pickpocketing a grenade onto them so you don't take a faction hit. Amazingly the dress will still be wearable.

If all else fails, use console command player.additem 001258c2 1 100 and say you found it in a closet.

If you do beyond the beef you get attacked by 2 white gloves, and you can kill them with no rep hit.

Right! I forgot about them. (I snuck past them. They are still waiting for me in that hotel room )

That's how I got mine. I also got a formal gown, which gets the same response from Veronica, but I have no idea where it came from...
