I'm a HUGE fan of the sheer trend this summer, as well as the sleeveless, collared button down. You can dress it down with bright bandeau underneath or by tying it in a knot with high-waisted shorts. You could dress it up with a tank top underneath and a blazer over the top. Here is a casual way to jump on the trend without over doing it.
