I wouldn't say that I love shorts but I've learned to like them enough out of necessity. I mean it gets freakin' hot here in DC & not just hot but sticky. All thanks to that good ol' humidity.
Boyfriend shorts can be a bit intimidating to style because they tend to lend themselves to a more relaxed look. For a more put together look try styling them with structured or feminine pieces. But also don't be afraid to totally roll weekend casual by throwing on a tee & your favorite sandals.
When selecting a size for anything that has the 'boyfriend' label, I always size down from my go to. Try on both sizes to see what works for you. I prefer sizing down for a slighter slimmer boyfriend fit.
