The color of the pajama can vary depending on the chosen print. While patterns dominate the design, the base color of the fabric can also vary.
Consider the occasion for which you plan to wear these pajamas. Some are designed for lounging at home, while others are more suitable for sleepwear.
Be sure to check the care instructions for your specific pajama set. Most can be machine-washed, but some delicate materials might require hand washing or dry cleaning.
