I wanted an over-sized jacket that wasn't too warm. I'm from the north but I now live North Carolina and the coats I have are too warm since the winters here aren't as cold and long as I'm accustomed to. This jacket has no lining so if you want to wear it for the cold weather you'd have to wear thick clothing underneath, this is perfect for me because when its cold i could put as many layers underneath and be warm & when the weather starts to get a bit warmer i could wear a t-shirt under, let the coat spill over my shoulder a bit and have a look lol
For size reference I'm 5'1 and usually wear x-small, I got the x-large because I have big boobs (30G) and wanted the jacket to be over-sized. If your the same size as me but aren't as big in the chest area i recommend getting the large if you want the over-sized look too.
Also I didn't know who Emma Chamberlin??? was until now but this doesn't really look like her jackets from her clothing line. Her's look like over-sized midi jackets, these jackets aren't midi at all but they're still cute.
