I just LOVE this blouse. Its not something I would typically like but theres just something about it!

Does anyone know how I would go about making the sleeves like that? I think I have an idea of how I could but it's probably not the same way that they went about it and I want it to look very similar when its done. (obviously I can't afford to buy this...I dont think I can really afford anything from Anthropologie! ) Sometimes they have some really cute pieces though!

I would say to use a kimono type cut sleeve, cut larger along the arm holes than needed, then gather them using a lose straight stitch then sew onto the body of your shirt.

its a raglan sleeve,  and I would think the arm hole in the body is  a little longer than normal, I think the sleeve is a full-length or longer sleeve, that has only had the underneath seam sewn together for about 1/3 to 1/4 of its length, the rest, forms a large arm opening, is gathered as amraann says, into the arm hole. the top opening appears to be finished with piping (cut a facing to match the top and insert piping between the facing and the garment)

the sleeve bottom appears to be gathered into a small band
