“When I first tried this on, I thought it was too large, but after washing, it fits just right. My chest measures 41", 38F, so I should be able to wear the large, but had to get an XL to button across the chest. So if you are between sizes and have a larger chest, size up. I absolutely love the length and the fact that the front is the same length as the back-so hard to find these days. The material is thick and warm, very high quality. I would give it 5 stars if I didn't have to size up to button the chest.”
