Eva Amurri Martino, 29
Body Type: Pregnant
"I'm learning how to dress for my new body shape," says Amurri Martino, who is expecting her first child this summer. "People say you can wear your regular clothes, but it's not true! Everything has to be longer, especially shirts. And I prefer to wear things that are tight around my growing belly so I can show off my shape."

What She Knows Works for Sure
Asos's maternity line ("They have really cool jeans and faux-leather leggings"), anything by Tory Burch. "Her pieces are feminine and pulled together, but not too girly," says the actress, who teams up with her mom, Susan Sarandon, in the upcoming movie Mother's Day.

O Creative Director Adam Glassman's Take

Look for stretch fabrics that will accommodate your changing silhouette. And resist the urge to hide in oversize clothes—they'll make you look frumpy. Sleek pieces (like this Elizabeth and James skirt) are more flattering.

If you're pregnant...
Don't cover up luminous skin. It's okay to flaunt lovely shoulders and décolletage.

Stick to neutrals or richer shades—they're more becoming than brights or metallics.
