I love this item.  I work 1-9pm in retail and the store is hot during the day but I often get cold after it gets dark.  We can't wear anything over our shirts and our shirts are so poorly made they fit weird if you wear multiple layers unless it's a men's large.  I decided to get this so I can wear my usual undershirts then add or remove sleeves if necessary. It works so well and looks great.  The ONLY reason I give it 4 stars instead of 5 was due to when I received my item,  I removed it from the zip locked it was in and it was damp.  I thought it was my imagination but sure enough I saw liquid droplets in the bag.  However, all the other packaging was fine. So gross.  Washed it though and moved on.
