I was so surprised by this jacket! i grabbed it as a last minute thought and then when i tried it on i was in love! i have a pink dress i'm going to wear it over but i also love it over a frilly off white tank or even just over a basic t. i am so excited for cooler weather. be warned its not lined or warm. its more of a shirt than a true jacket but it's perfect for fall in california. i wear a small or m and went with a medium on this one.
