Class, Appearance and Dress Codes
As in many Latin American countries, how you dress and your overall outward appearance is extremely important. The Dominican Republic maintains class divisions, many of which are determined by race, familial heritage, and financial status. This is not the case in more cosmopolitan cities and densely populated urban areas.
As a result, you should be aware that clothing is thought to be one of the most important indicators of social status, which in turn denotes accomplishment and success. Designer brands are particularly popular, but this does not imply that you must wear them all of the time! In general, dressing modestly and attempting to appear smart and well-groomed - even when dressed casually - will be perceived as upholding your personal appearance and self-respect.
Beach and swimwear, such as bikinis or swimming trunks, are perfectly acceptable for wearing on the beach, but should only be worn on the beach. Swimwear should never be worn in public, including cafes and restaurants. If you intend to eat out while at the beach, bring a change of clothing and keep in mind what is considered modest and appropriate casual wear.
