See bottom of post for update.
Anthropologie's Aniseed Skirt originally retailed for $128 and is currently sold out online. (Check it out on Emily at Cupcakes and Cashmere HERE.)
I love the blog Effortless Anthropologie and when I read a tweet she sent out this morning, I had to go check out her newest post. This skirt she found at Modcloth retails for $41.99 and you can click here to purchase. While you're at it, head on over to Roxy's site for more amazing Anthro alternatives she found recently. Now if you'll excuse me, I need to contemplate whether or not to order this adorable skirt.
*Update - 6/14/10* - I saw this dress on Lulu's and although it's more "inspired by" because it's a dress and not a skirt, I thought I'd post it for those still looking for an alternative to the Anthropologie version. It retails for $52 and you can click here to purchase.
