Short answer, no we didn't consider sleeveless. We did do a tank in one design, but no sleeveless. We'd either need to use a different vendor OR work with Primal on pattern development, because Primal does not currently have a stock sleeveless pattern. I'm sure we could develop one with them, but in this case, we wanted to get these done before the summer was up which precluded pattern development. Perhaps for 2013. (Thanks for the zipper feedback. Will pass it on to Primal. I didn't notice it myself, but my girls have no trouble filling out the jersey... ;-)
