So many people wear black and neutrals, but it's really fun to play with color," says Lindvall, 33, of the tangerine and lemon brights she models here. The produce she's pushing isn't just for show, either: "I live on a small farm and grow vegetables in my garden, so I'm a big supporter of sustainable local agriculture," she says. "It's something I'm really passionate about."

Candy Stripes
Amp up the deliciousness of a watercolor skirt (Teri Jon, $220) by pairing it with a bright blue sweater (Katie Ermilio, $695) and pink cardigan (J.Crew, $90) instead of the expected neutral. "This is really cute and girly," says Lindvall, who started modeling at 14. "I've always been a bit of a tomboy, but since I became a mother, I've developed my feminine side."

Earrings, Lydell NYC, $16. Cuff, Presmer, $89. Ring, Roberta Chiarella, $88.

Tips from O Creative Director Adam Glassman: While pink is flattering to most skin tones, mix the shade with other colors to avoid a Barbie look.

Sugar Rush
A hard-candy-inspired top (Karen Walker, $165) gets even sweeter when belted over a floaty pink silk chiffon skirt (Heidi Merrick, $312). "It's okay to have candy every now and then," says Lindvall, mother of two boys, Dakota, 9, and Sebastian, 6. "It's an indulgence, kind of like fashion."

Bangle, Robert Rose, $25. Silk and Wool Bangles, Rosena Sammi, Starting at $45 for three. Necklace, Robert Rose, $28. Watch, Michele, $1,715. Ring, Robert Rose, $23. Clutch, Kate Spade New York, $358. Shoes, Nina, $100.

Mint Condition
A pale green blazer (Diane von Furstenberg, $425) and rosy pants (3.1 Phillip Lim, $475) look anything but preppy when accessorized with an edgy periwinkle blue Inge Christopher clutch and Brian Atwood stilettos. "I love these color combinations," says Lindvall, who designs Angela by John Hardy—a jewelry line inspired by her travels to Bali and Thailand—for QVC.

Shirt, Rag & Bone, available as a dress, $415, Neiman Marcus; 800-365-7989. Sunglasses, Dolce & Gabbana; $360. Necklace, Pono by Joan Goodman, $215; 203-340-0764. Ring, Dara Ettinger, $105; 718-875-3272. Cuff, Elsa Peretti, Tiffany & Co., $825. Belt, Ann Taylor, $30. Watch, DKNY, $115.

Tip: Wear colors of the same intensity, i.e., don't mix brights with pales. Accessorize with neutral or metallic pieces—but stay away from black, which is too harsh for these looks.

Power Puff
"This look is my favorite," says Lindvall of the ladylike Katie Ermilio sheath ($1,250). "Powder blue is my kind of color—I tend to go for more muted color when I'm not working." Tribal-inspired DKNY platforms add a fun, unexpected touch.

Necklace, Swarovski, $700. Belt, Meredith Wendell, $285. Bracelet, Roberta Chiarella, $58. Ring, Dara Ettinger, $144; 718- 875-3272. Ring, Marlyn Schiff, $54. Clutch, Tiffany & co., $895; 800-526-0649.

Tip: Save the kitten heels for another day. Harder-edged shoes keep colorful looks from becoming too saccharine.

Lemon Drop
"The beadwork is really beautiful on this dress [Chris Benz, $1,395], but there's also an element of easiness," says Lindvall, who is putting her attention to detail to good use on Project Runway All Stars. "Having been in the business for a long time, I've really got a sense of what works and what doesn't."

Earrings, Fantasy Jewelry Box, $27. Watch, Pedre, $100. Ring, Robert Rose, $18. Bracelet, BCBG Max Azria, $88. Clutch, Blues by Kyky, $325.

Cool Whip
"This is something I would wear to a wedding party," says Lindvall of her 2b.RYCH jacket ($352) and pale green sequin skirt (Diane von Furstenberg, $695). "It's really pretty and polished."
