Love this jacket! However, it runs incredibly small! I'm 5'5", 130 lbs and normally wear a size 8. The specs for this jacket said small fits 8-10. I had read reviews that said it ran small, so I ordered a medium. It was very snug around the bottom and even the sleeves felt tight, even without a sweatshirt or anything heavy underneath. So I ordered a large and it fits perfectly. The Omni heat lining does a great job and is very light weight. It's just a jacket so it doesn't cover my backside at all, so if the weather is under 30 degrees, I wear a longer coat. I also love the color - purple, but not too purple.Warm yet not bulky. Comfortable. Unique color. Nice hood. I wish the elastic at the sleeve cuff wasn't black and matched the elastic at the bottom of the coat. People were saying the cost runs large so I ordered a medium and large. I usually wear a medium and it fit. The large was too big.This is a really nice jacket and I love the fit, but it's definitely more purple than I expected. I was expecting more of a navy as the color is called Ink. I'm 5'5" and 145lbs and the medium fit perfectly.Nice and warm. Size run small. So after I read the reviews i take the chance and my regular size is Large so I order XL and yes perfect for me. Recommend to everyone.This fits perfectly and its keeps me warmer than any other jacket I've ever owned and it arrived right in time when our temps were single digits. I would recommend this to anyone.Nice and warm. Sizing is more like Juniors.Its good to useIncredibly warm for a light-weight jacket and really cute. Seems to be true to size as well.
