Mom-to-be Jessica Simpson is still rocking spring's It bag -- the fuchsia Celine Luggage tote (celine.com) -- but her trademark heels are a casualty of pregnancy.

"I'm flat-footed, so cute flats and ballet slippers are comical on my feet," the 31-year-old star tells Us Weekly. "People actually laugh at how I look and walk in them, so Havaianas flip-flops (havaianas.com) are the only way to go. I actually had to train myself to walk in them!"

Below, the cocreator of the customizable skincare line BeautyMint shares her other must-haves.

"I always carry three pairs of sunglasses in my purse," she shares. "I just got a new pair of Victoria Beckhams that I love!"
