My husband has got a proper eveing suit with bow tie for the formal evenings, but on the informal & elegant casual evenings, he can wear suit & tie & the just the suit (no tie) for elegant casual.

My question is this; can he wear his evening suit with a regular tie and without a tie for the informal & elegant casual or does he need to take a second plain suit with him?

Both suits are quite heavy together and as we are flying home, we have weight restrictions!

Any advice would be appreciated (sailing this saturday from Southampton, soooo excited)

Thank you
