This is Burdastyle 126 from February of 2013. It's your basic raglan tee, but you gather the edges of the sleeves on both sides before sewing them to the back and front. The design detail shows off better if you don't use a patterned fabric, like I did.
|Not much clearer in the closeup, is it?|
My pattern review is here on PatternReview.com, and there's more chat on my blog.
