Valeria Tunic from Anthropologie
You can do your best to borrow a men's shirt and make it work for you, but it's much easier just to be buy a menswear inspired top with feminine fit and charm. The Valeria Tunic by Edme & Esylite and available from Anthropologie, has the same look in a great shape. Totally versatile, you can pair it with cutoffs and flat sandals or buy-now-wear-later and throw it over leggings and tall boots.
