Muslin swaddle or fleece blanket to bring baby home in?

So our little girl is due July 18, it’s already pretty hot where we are and I was just wondering what kind of blanket I should be packing in my hospital bag for baby. I love the muslin swaddles but they are so expensive. Are they really nesessary. We do have a cute fleece blanket we had gotten for her but I’m afraid it might be too hot. Although I do know babies can’t maintain their temp so maybe it won’t be too warm?
