What should I wear when meeting a Dubai escort for dinner?

Smart casual is the Dubai standard. A clean button down shirt, good trousers, and decent shoes. No suit needed unless you are going to a very formal venue. The companion will dress to match the restaurant so you should look appropriate for the same setting. What matters more than your outfit is your grooming. Shower, clean nails, deodorant, subtle cologne. Your companion notices hygiene before she notices your brand names. Confidence in what you wear matters more than what you actually wear.
