These are some of the sweetest socks I've ever seen. I love the loose fitting cuff, the contrast stripe and the tiny wee bow at the back.
The Vintage Flower Socks are £14.00 from Tabio.
Note: Although the website states that they do not ship internationally, I've been in contact with their lovely and very helpful customer service person who assures me that they do in fact accept international orders. Simply email them at firstname.lastname@example.org for an order form which you can fill out and email back, or they also accept phone orders.
