DD1 has 1 hand me down nightgown and I usually let her wear it with a random pair of PJ leggings. We live in the USA-NE so I don't think I'd let her just wear the nightgown with no pants, esp since she kicks off her comforter.

She is asking for more night gowns but I'm hesitant because then I'm always pairing them with random PJ bottoms, thus breaking up the other sets? Am I way overthinking this??
