Thanks to the reviews here, I went and ordered some bows from Val's Diva Dos, and her bows are sooooo cute.
I ordered them in french barrettes and they're perfect. I can do the topknot, then clip in the bow. If Bitsy changes outfits, I can just take out the clip, and put in a new one without having to redo the whole topknot.
Also, if you mention you're a YT member, she'll give you a 10% discount.
