Call ahead and find out which stores you need to make appointments in.

Wear comfy shoes and suitable underwear (white!) to go under different styles of dress.

If you're going to a place that has a wide selection of dresses, leave about two hours before you make the next appointment.

Bring phone numbers for all the stores you have made appointments in, in case you're late, or need to call for directions.

Don't expect to fit a huge amount in and only visit stores within a short distance of each other.

Allow for sterling - the rate is dreadful, but you could still find your dream dress is cheaper than the one you've been eyeing up in Dublin.
