I recently bought several pajama sets (I am traveling and wanted something I could wear comfortably without a bra in the presence of family and friends). These new pajama sets work well for that purpose. They also have a crispness that makes them look somewhat dressy.

The bottoms will need to be laundered more frequently than the tops. My question is do you launder both items at the same time or do you just launder the bottom and wash the top when it needs it?
