Considering the Continental Hotel in Santo Domingo?
A VT member wrote the following comment about visiting Santo Domingo:
Dress by el_ruso
If you don't want to stand out too much from the people, very few people wear a t-shirt, and noone except for a couple of odd tourists wears shorts.
Men wear either a polo or a botton-down shirt, often untucked, and jeans. Women dress very provocatively, but never sleezy or cheap.
