Nina Agdal is heading off to the gym in this outfit, but I think this ensemble could work for a casual day on the town. Here is a recreation of Nina's chic and casual model-off-duty style for much less.
I'm pretty sure she is wearing a pair of sneakers (since she is heading to the gym) even though you can't see her shoes in this picture. If you want to make this more of a casual summer outfit (not a gym outfit), a pair of simple black booties are perfect for this ensemble.
To complete this look, grab a brown and black satchel to carry all of your essentials. Now you are ready to rock a chic and casual ensemble that will make all of your friends jealous!
