DS is 3. Very particular about clothes, and very into a character. I have found character clothes, but they are pajamas. We don't have non pajamas clothes for this character. I haven't found any yet that meet DS requirements.
The tops are fine as you wouldn't know they're not t-shirts. There is one pair of shorts and one long bottoms, both of which look a bit more like pajamas.
I think that DS is very little, and I think at this age, if he wants to wear them during the day (to be clear, I mean just using them as day clothes, not letting him keep them on after wearing at night!) it's fine, and neither he nor I will care if people know they are pajamas. DH thinks it's not OK and they should just be kept for bed.
AIBU to let him wear clean pajamas in the day as day clothes?
