How do those pregnant celebrities always look trendy, yet totally polished? Pregnancy Fashion.com is going to share a a few of their maternity style secrets with you, from InStyle Magazine. These tips will keep you looking as hip and pulled-together as actress Jennifer Garner (in photo).

Sleek Silhouette: When dressing up, wear bottoms that rise over your belly for the smoothest lines under tops.

Splurge on basics; skim on trendy items: Forget about blowing your budget on that one funky printed tunic top like Gwen Stefani. Spend your money wisely on a great-fitting pair of jeans, some well-tailored work pants, and empire-waist tops.
Add color with fun, funky accessories: When wearing basics, make a statement with jewelry like bold necklaces or cocktail rings, which can be worn post-pregnancy.
Keep it balanced: Wear dark-wash maternity jeans with long, thin legs to balance out big tops.

Shop eBay: You can find designer maternity items at a fraction of the price through consignment shops and eBay. And, when you are no longer pregnant, you can resell them!

Budget shopping secrets: Comparison shop online for those must-have designer items to get the best price. When shopping at pricey maternity boutiques, walk past the high-dollar items at the front of the store and peruse the sale items at the back of the store. You may get lucky and find a real steal.
