How I Met Your Mother actress Alyson Hannigan celebrated the return of her show with an early St. Patrick's Day party. Though there's no green in sight yet, there is teal — her B. Romanek python clutch. As always, she looks graceful in her Vena Cava keyhole dress. Her slingback peep-toe pumps are pretty, but I gave her a chunkier shoe to balance out the feminine dress.
