This jacket is so cute!! It is on the thinner side but not extremely thin in my opinion, I think it’d still do a decent job at keeping you warm especially if you layer up with like a long sleeve underneath. It’s not ideal for extremely cold weather but it’s also not useless, I’d say it’s ideal to wear during fall. It fit true to size on me although it does have an oversized look to it. Overall I love it 10/10! Looks just like it does on the model.
