so does this mean we don't need Dress clothes?

We will be going on an early September Alaskan cruise and I need to start packing. My question is what do I need to pack for the main dining room. The last Alaskan Cruise we did was in 2011 on Princess and we overpacked for dining. Most people wore casual clothes. Trying to pack for cold weather and possibly warm weather and bringing jackets and raincoats, how much do people dress up for dining? Thanks for any information
