PJ suggestions

First time mom looking for recommendations on pj’s mainly for the spring. We don’t turn our AC on right away when it starts to warm up, just opening windows and have fans on. But it still can get a little warm in our house, especially on the second floor where the baby sleeps. She was a tiny preemie when she came home in August so we’ve always been able to get away with long sleeve footie pajamas but I worry about her getting too warm now that the weather is changing. What does everyone else put their littles in for bedtime?
