Princess Lodges-Dress codes for dining

Does anyone know the dress codes for dining in the Princess Lodges' dining rooms? In other words, is it still resort-casual as it would be for non-formal nights on the ships, or can jeans be worn? Thanks for any advice.

It was pretty casual.

Alaskan "formal" is jeans.

I sent all my "resort casual" clothes directly to the ship, and lived in jeans on the cruisetour. I never felt out of place.
