I recommend these stylin' white flat macrame shoes I bought at H&M last week for only $14.99. What a steal! So far I've worn them with a royal blue maxi skirt, a short lacy white dress, basic jeans, and white pants. They really do go with everything spring!
Although I can't find a link to the exact H&M shoes (damn you H&M for not selling your products on your site!), I found similar white macrame shoes at Kmart.
