This Oversized Shirt Dress Is A Classic. Looks Great Belted Or Without A Belt. It’s A Light Poplin Fabric That Would Be Good In All Seasons. This Is A Size Xs But Pretty Oversized. I Normally Wear A Small In Jcrew And It Is Still Oversized On Me. Depending On How Big You Want It To Fit - It Could Fit A Size Xs, S, Or M. For Context - I Am 5 Ft 8 And Wear A Size 26 Or 27 In Jeans.
