What I would...

do, wear, serve at a Summer Backyard party

Not that you asked for my opinion but let’s have fun. Place the lemonade rosé on a chic tray and lets host. Whether you are at a lake house, in the backyard, or around a simple dinner table, this is exactly what I would do. Not trendy. Not complicated. Just beautiful, intentional, and have your guest not wanting to leave (at least until you kick them out).
