She may not be rocking sky-high heels like Beyonce and Jessica Simpson, but Reese Witherspoon is taking the much more comfortable (and probably safer) route with her maternity wear.

From running errands in raspberry-colored frocks to rocking black Stella McCartney couture on the red carpet, the 37-year-old star, who is expecting her third child (and first with hubby Jim Toth), has been having fun mixing up her wardrobe. (Her brood already includes her children Ava, 12, and Deacon, 8, with ex Ryan Phillippe.)

But loose-fitting cotton dresses aren't the only ways she's dressing up her bump. In early April, Witherspoon dropped a pretty penny -- $600 to be exact -- on three pairs of maternity jeans at an L.A. Paige Denim store. On her shopping list: the Union Ultra Skinny in Caress ($199), Union Skyline Skinny in Capri ($199) and Union Skyline Ankle Peg in Optic White ($189) -- all featuring inset elastic panels at the waist for added comfort.
