Her curled-under bob
To get a subtle curl like this on the ends of your bob haircut, "use a large-barrel curling iron on a medium heat setting or big cloth-covered hot rollers -- medium to large size," says Dickey. (Try Conair Infiniti Flocked Rollers, $47.99 or one of these top curling irons.)

Her perfect flip
To get an all-around flip, clamp hair ends into a jumbo ceramic curling iron and hold for a few seconds. You can also use a 1" flatiron (find a good one here), flipping your wrist outward as you reach the ends of your hair. Set the flip with a strong-hold, flexible hairspray (try Sebastian Shaper Plus Hair Spray, $14.99).

Her glowing skin
Get radiant skin from head to toe by moisturizing skin, then applying a luminescent powder (MAC Mineralize Skinfinish Powder, $25) on body, arms, chest and legs with a fluffy powder brush (try Urban Decay Good Karma Powder Brush, $35). On darker skin tones, use a powder with golden or warm bronze tones to avoid looking gray or ashy, Jennings says.
