I ordered the girls ears from the online store last year. I think I paid around $4 per set of ears for the embroidery. In my nearly 2,000 pics from the last trip- I can't seem to find any pics of the embroidery . If you want to see what it looks like from ordering online- let me know and I can take/upload some pics to this thread.
Wait- I found a partial pic. Sorry...not a great pic, but it should give you a good idea of what they'll do if you order online...
and another from farther back...
This was online at the Disney store?
