I couldn’t decide if I wanted this little jacket and finally purchased when I saw it on sale. I usually wear a small in tail tops but went with a medium because I have longer arms. Wow! It’s perfect. Love love love. I’m 5’8” 128lbs and the medium fit perfect including the sleeve length. I live in florida so leather is just not practical. This is perfect for cool nights with white jeans or black pants for dressier look. It would also be great to travel because of the material. So happy I purchased this. I’m tall and lean so I think sizing up is a good call.
