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!
