Hot in Street Style: "Twin" Dressing

It used to be "don't" to have someone else dressed similarly to you. Now the more matchy-matchy, the more fun. (Yup, the blonde duo in '50s-inspired frocks at the bottom are the Hiltons.)

The hardcore way (from left): United in bunny ears and denim, gypsy-inspired gear and,
uh, are we seeing double?

And a little less so: Same (print), but different (silhouette)...

... From left: Matching collars, '50s style frocks in the same family of colours,
and fringed leather skirts
