Sleeping outfit

What do you dress your newborn in to sleep at night? Our bedrooms get pretty warm so not worried about baby getting too cold.

I’m just struggling to find gender neutral newborn sleepers, I have 3-4 currently. But how necessary are they for newborns? Once we know the gender and have the baby shower I’m sure I can easily buy a few more.

If I swaddle, could baby not sleep in just a body suit/diaper shirt? FTM at 30 weeks, and I’m just getting a little anxious about making sure I have enough clothes for the first few weeks! Thanks 😊
