Chew Chew's Closet on etsy, even though they are technically meant for children?
One perk about the kids thing is that they are made extremely well and the clip is enclosed in fabric, so gals with fine hair won't get their hair pulled out (I hate that!). If you have super thick hair you might want to request a custom piece made with a jumbo clip.
Another perk is that they are super affordable. Most clips are between $4-5. I just love this heart clip, don't you?
Personally I would plan an outfit around these cuties...
