Rompers. Yes, they're trendy. They are also really comfortable and really great for travel. Evidence: see photo above of me with my husband in Ostuni, Italy.
If you don't have one, get one to wear for the rest of summer. You can find a normal one that you could wear to the grocery store without looking like you are going to Coachella. Or if you want to look like you are going to a festival (I understand!), you can find that too. Yes, some of these are $100.....but it's an entire outfit!
