Oasis - Dinner attire

[babscruiser]

We will be taking a cruise in the Mediterranean in late August on Oasis of the Seas.    At dinner in the Main Dining Room, will we need any dressy clothes - jacket for the men, dressy dress/pants for the women?   What about on formal nights ( if there are any)?         [We usually sail on the Cunard ships where dinner attire is  required in the dining rooms, so we need some clothing advice from all of you as we are traveling on a different cruise line.]    Thanks for your input.     Babscruiser

WHile there are formal nights, Royal does not enforce dress suggestions, so you will see the full range of attire.  You can wear whatever you like.
