Newborn in the summer

Okay I feel dumb for asking this but...for those of you that had babies in the summer...what do you dress your babies in? I found out I’m having a girl (I already have a boy) in June and I’m stoked and want to buy clothes. Part of me is like, “it’ll be hot and in the 90s and I should get short sleeved stuff.” Part of me is like, “she’s going to be so fragile and little and freshly ripped from my womb. She’ll want long sleeved sleepers.” So which is it? I really have no idea how to dress a newborn in the summer. My son was born in late fall so I just bundled him up. Thanks!
