Comfort-Focused Pajamas with Non-Constricting Waistbands

The user explicitly states a strong dislike for tight elastic waistbands on pajamas and is actively seeking comfortable, loose-waisted options. The only suggested solution ('Size up') is often inadequate as it doesn't address the fundamental design issue. This highlights a clear product opportunity for a brand or line of sleepwear specifically designed with innovative, non-constricting waistbands. This could involve wide, soft fabric bands, adjustable drawstrings without elastic, or extremely low-compression elastic to provide comfort without tightness.
