We received a number of inquisitive e-mails regarding the yellow bow pumps featured in the Spring/Summer issue's fashion spread "Summer Champ." You can find the butter yellow at Mode Boutique...
But, if you are not local (Hello Singapore!) I found them in a variety of colors on a two international sites.

1. Nordstrom
2. Endless Shoes and Handbags
Now your only problem is picking a color!
