Clothes for a Summer Newborn?

Becky

Hi ladies! First timer here. Baby Girl is due on June 10th. I have some hand me downs from friends in 0-3 months, but I'm not sure if I should be looking for long sleeves and pants, layers, or short sleeves. Average temps here will be between 70 and 80 for June. I plan to start scoping out some second hand sales and want tips for what to look out for.
