I'm in the same boat here - busting out of my smaller stuff...and most of it is too hot. I did get a shirt for my shower tomorrow, but have no clue what I'm wearing on the bottom half? Denim capris are about it...ugh. Guess I'll have to get something today...? Ugh, again... It gets hard at this stage.
I've had one June baby before, but it was almost 12 years ago.

During sleep times, I remember putting him in the lighter sleep 'n' play footed sleepers and using a light receiving blanket to swaddle him. Once you figure in the a/c, there is enough of a "chill" to do lighter long sleeves indoors. For this baby, I do have several really cute onesies (outfit-type) and outfits that are more "summery"...I can either layer over them or use blankets as needed. I plan to do a lot of babywearing, too (pouch sling early on), and that will keep baby cozy.
