This is the coolest hoodie! I recommend sizing up. I currently wear either a size 6 or an 8 depending on brand. I am 6ft and 135lbs. I ordered a large and it fits perfect over my little guy and we have some room for him to grow! Remember this has to fit over your frame and your child's along with a carrier. The arms will fit anyone. They have cuffable sleeves that kinda remind me of those grow with me pants for kids. The hoodie is long but it works and looks great. You want your little ones feet inside the hoodie. My only complaint is how bulky the cowl neck is. It's such a neat feature as it is can be used as a hood also... however the material is thick and it's very bulky. This however would not deter me from buying this product or wearing it. If you are looking for a very warm outdoor option to wear over you and your child this is perfect!
Thank you so much for your review! I'm so glad you are enjoying it <3
