If you're one of the moms-to-be who are sticking with a closet of baggy t-shirts, oversized cardigans and flowy tunic tops this season, it's time to take things up a notch and dress up in one of Spring's pretty dresses! Pregnancy can take its toll on your emotional health and well-being, and dressing up a few days per week can help you get your positive energy back! Here's a close look at some of the season's hottest dresses in the maternity department:

Maxi Dresses: The Maxi Dress is the perfect cover-up for the mom-to-be who wants something that isn't cut to fit too tight, and still looks fashionable. Maxi dresses are designed to flow outward from the bust line downward, and will give you a nice silhouette. Pick yours in a dark jewel toned color for a sophisticated and classy look.

The Tunic Dress: The Tunic Dress is a must-have for any mom who wants to relax during the day but still look pulled together. These dresses are designed to flow outward from the waist and won't cinch or pinch in any way. Get yours in a bold Spring hue, or go for a geometric print if you want something more eye-catching.

Printed Halter Dress: The halter dress gets dressed up this season in bold, vivacious prints. Enjoy your day shopping around town or relaxing with some girlfriends in a black and white, red and white, or splash of tropical colored prints that are aligned with this season's trends. Look for Asian-inspired prints such as lotus flowers, Chinese calligraphy and orange blossoms for an extra fashionable touch.

The Front-Tie Dress: When you're looking for a simple and stylish look for the day, go for a front-tie dress designed with an extended waist tie that goes right over the baby bump. The flattering cut and wide elbow sleeves like this Maternal America Front Tie Dress are perfect for days that demand a casual but chic ensemble.

¾ Sleeve Empire Waist Dress: The empire waist dress is a super-flattering cut for moms-to-be at all stages of pregnancy, and you need to pick out yours in bold prints and Asian-inspired designs. Look for one with a ¾ sleeve that works well for both day and night.
