Critters in clothes prove true creatures of fashion

These clothing designers have to think about pattern, fabric and fit - as well as where to put the poo bags.

Creating on-trend outfits is a whole different animal for pet fashion designers, whose work is becoming mainstream as animal lovers look to further pamper their pets. For some owners, it's a statement; for others, it's a way to match man's best friend; and sometimes it's simply about keeping animals warm this winter. But it's clear the number of dressed-up dogs and cats jumps significantly once holiday photos need to be taken.

"We have gone from the kind of cute reindeer gear or ugly sweater to more functional clothing," says Lauren Darr, founder of the International Association of Pet Fashion Professionals in New York City.
