Dress code for Vantage cruise?

[cruising camper]

We are cruising from Amsterdam to Basel with Vantage in September. I have read all the info they sent us and haven't been able to find any info about dress code. I am familiar with dress codes on ocean cruises but this is our first river cruise so I would appreciate any info previous Vantage cruisers can give me. Thanks!

Dress is very casual. Most people do not change for dinner. People dress up a little more for the Captain's dinner. If the program includes a dinner at a restaurant in town, they may suggest that you might want to dress up a little. On those occasions, some of the men wore jackets (not all) and the ladies wore slightly more dressy tops and pants for the most part.

:)Thank you for the info. My husband will be so happy to read your reply. He dressed up all his professional life and now that he is retired he doesn't like to.
