Linda and I are going to be owners of an abaya as well. We also are on the same excursion Olivia so we will all be in our black robes together. I also feel that if I am there I want to go ashore and see something of the country. Everyone just has to make their own decision.
We have had to wear similiar clothing before and it really was not that big a deal. Ken and Ron had to wear the robes too so we four were all "robed" together.
