What are some baby must haves for moms who live in hot climates?

I live in SW Florida and it's freakin' hot here!!! We keep our AC running year round at 75-78 all day. I'm in the process of collecting clothing and taking advantage of the after Christmas sales for my twins whom I'm expecting in April. I feel like some of these clothes are just too hot for babies to wear in Florida, even in the winter!! What did your babies wear? What are some other must haves for babies who live in hotter climates? I have been just buying onesies. Should I buy pants? PJs? Any other recommendations? I'm clueless.
