Maybe it's because I had to wear a uniform in high school and thus felt like the only way I could express my personal fashion during my formative years was through my footwear, but I've always had a soft spot for cute and quirky socks. So I was delighted when I found the cute-sock-intensive website Sock Dreams.
They have so many lovely styles of socks, tights and stockings - not to mention accessories like arm warmers, sock garters and gloves - all helpfully organized by style right on the front page. Are you looking for anklets? Thigh-highs? Knee socks? Over-the-knee socks? Fishnets? Something holiday-specific? It's all there and easy to find!
For instance, right now they're featuring a link to a page showcasing all of their green socks, just in time for St. Patty's Day. It may sound a little kitschy, but how adorable are these green-on-green Rugby Striped Knee Highs?!

On a non-Irish note, I also love these crocheted trouser socks in burgundy:
I already have a few pairs of over-the-knee socks from the site, including the O Basics (in Violet) and the O Chevrons (in Red/White), so I can personally attest that they are, in fact, super comfy and flattering, not to mention amazingly well-priced. Plus, with so many styles and colors to choose from, it's easy to spend an entire afternoon just browsing through their site, admiring the pictures and putting together outfits to go with the socks in your head. Have fun!
