Ok.. so this is the time of year that things start sweltering. The major heat rolls in and fashion seems silly.. because being in the water seems to be the only good option.
If you do have to leave the water and head to land in this heat, than I suggest wearing a easy-but-statement sundress. Pair it with a big floppy hat and sandals.. and call it a day. Find some shade, pack a picnic and do summer right.
