My preemie just came home/room temperature

I have my AC in the window but I'm keeping it on fan. The AC says 72 degrees and it's blowing warmish air. The baby has on a short sleeved onesie and she is swaddled in a receiving blanket with her hat on and a pair of socks. I don't want her to get too hot or too cold. Is this good wardrobe for her? And a good temperature? Any suggestions? Will I be able to put my AC on cool? But if so what do I dress her in? This is my first baby so I'm new to all of this, any advice will help thank you
