Go for a Hawaiian or Luau theme for one of the days. We did this the past couple of years and it was a hit. This year we also changed the room for second day to a Hollywood theme, it was a lot of work to seitch the room halfway through recruitment, but it was well owrth it because all of the pnm's were impressed we took that effort. I'll put what we wore for each day below.
Hawaiian:
khaki pants or capris
brown sandals
Bid day shirt or bright letter shirt, depending on how many days you have for recruitment.
Hollywood:
white or black dress top
black or white pants
(example: wear white top with black pants; black top with white pants
black sandals
Pref:
Our chapter traditionally wears black dresses and shoes for pref.
If you have any questions feel free to PM me.
Hope this helps.

P.S. I might be able to think of some other ideas, depending on how long your recruitment lasts.
