If you want to have some show you dresses and try them on "yes" you need an appointment. If you just want to walk in an browse no you don't need an appointment
No! You don't need an appointment to look around or shop, but you may not receive the help you're hoping for if they are booked solid. Plus, they do a deal sometimes that gives you a discount for having had an appointment. But if you just want to browse or you're starting your search for a dress or some accessories, you can just shop :)
