I bought this a jacket a size up (I am usually a M and purchased an L)  It looks great to wear open over an outfit as a cute spring/fall look.  However, this jacket is still extremely tight around my hips if I tried to zip it up.  I would order 2 sizes up to fit as a closed jacket, and maybe even 3 if you want an oversized look.  Other than the sizing, I love the jacket. It is a good quality light spring jacket.  The lining is smooth and comfortable. I like the drawstrings at the waist to add some definition.  Despite the sizing issue, I do not regret this purchase at all and have been wearing it multiple days a week as a light layer.
