The sleeves were much looser with this than with all the other Sleevey Wonders I've bought. I don't know if this was a factory defect or, if someone else ordered it before me and sent it back after stretching it out over their arms in an attempt to deny that they wore a larger size? Still, I am totally in love with Sleevey Wonders and will probably buy one of every single size, color and material they make.
