A navy blue satin night suit with a robe sounds luxurious! The smooth texture of satin adds a touch of elegance and comfort, perfect for lounging or a cozy night in. You might want to look for features like:

• Top: A button-down or pullover style with a relaxed fit.
• Bottoms: Either pants or shorts, depending on your preference for warmth or breathability.
• Robe: A matching robe with a tie waist, perhaps with pockets for added convenience.
