It's a Large size a Woman can fit as well as a older child can wear this. It can fit my 10 & 13 year old girls my oldest girl is 5'4 I'm 5'5 it fits us perfectly fits my 10 year old as well pretty good but definitely a woman can wear this Vest coat.
I'm not going to tell you yes because I'm not sure all I know this is a large size coat my sister is a large or extra large depends on the size of the clothing. All sizes are not alike. Honestly if I could see your size I would know. If you where a medium yes you are able to wear this.
