Huge sunglasses . . . check. Messy hair . . . check. London . . . check. Hmm, but what's this I see?! A cute, stripey top (on the dog). After some searching, and much zoom-in examining, I was shocked to find the Houndstooth Striped Sweater by DC at Petco on sale 'til 1/31 for $7.50 (originally $14.99). I'm wondering if Brit picked it up waaaay back when she also bought a goldfish at that shop . . . and a bit curious about the serious downgrading from the Kwigy-bo carrier and Little Lily dress we've spotted in the past. I couldn't bear to let lil' London wear something so basic, so see the more paps-worthy version (at twice the price) I've picked when you read more.
IMO, this heart rugby sweater is much more pantworthy. . . but let me know what you think in your comments below! 
first, i'm not a dogs in clothes kind of person. that said i would go with the petco version because it simpler. all he needs is a beret and baguette!
