If you look at the following shop:
http://www.etsy.com/listing/94735646/headband-flower-headband-baby-headbands?ref=af_circ_circleyou will see above the "add to cart" button, the ability to select the size you want.
How did I miss this? I don't see the ability to do this in my shop, so how in the world is this shop able to do it? I need this because currently the customer has to put the size in the comments section.
Can anyone help? Thank you!
