Head over to Macy's Herald Square this Sunday to see all sorts of animals dressed up in crazy outfits during the 9th Annual Macy's Petacular. And if you can successfully put your pets in a clothes, you can have them enter the competition - registration begins at 10AM, with the runway walkoffs at 12:30PM. This weekend is also the opening of the famous Macy's Flower Show, whose theme this year is Gardens of Fantasy, with eighteen different gardens in the store. Tons of people come to see the flowers, so be prepared for crowds. If you want to shell out $35 (for adults; $15 for kids), you and your pets can see the Flower Show at 8:30AM on Sunday (it's the Barkfest), plus chat with a pet accupuncturist and more. Gothamist will try to make it for the pet fashion show, but in case we get caught up in March Madness, let us know if you go and take pictures!

Oh, and Mischa Barton will also be at Macy's this Sunday at 1PM - she's the new face of Keds.
