Going home outfit for Texas heat?

FTM here, as I’m sure will be obvious as soon as you read my post. 😂 So I’m due July 26, and we live in Texas so it will be HOT. I’m trying to pick out a going home outfit but struggling. I know newborns don’t retain heat as well as we do, but it’s going to be hot as hell anyway! Do I pack a onesie and pants or a romper? Obviously I’ll have a blanket with me to put over him since we’ll be blasting the AC, but I’m just so paranoid if I bring a romper he’ll be too cold! I’m sure once I get to know him a little better and learn how he tolerates different temperatures it will be easier, but for now I’m stumped.
