Staying stylish during the dog days of summer when you're expecting can be challenging, especially if you're in your third trimester and are experiencing the aches and pains of pregnancy. It's very important for the mom-to-be to stay cool and relaxed under the summer sun, so choosing the right type of clothing is a top priority. Since you want to be stylish too, here are some of the best clothes to add to your summer collection:

1. The maxi dress. Super soft and lightweight materials make the maxi-dress a definite yes for the season. You can relax in these long, loose, flowing dresses designed with tropical prints or a Grecian-inspired cut for a romantic look. Add a pair of gladiator flats or kitten-heel sandals for a complete ensemble.

2. Maternity capris. 'Tis the season to show off those gams, so don't hide in drawstring pants or jeans this summer! Wear some capris for casual days at the office and weekends, so you can work up a tan on those legs. Maternity capris made with stretch material are comfortable and stylish.

3. Relaxed button-down shirts. Loose and flowing clothing is the best match for a mom-to-be, especially on days when you're feeling bloated and tired. A loose-fitting button-down shirt will help you stay relaxed and comfortable all day long. Choose a light-colored shirt to help you beat the heat this season, without compromising on style.

4. Loose skirts. This season's frock-style skirt trend is at the top of the must-have list, which makes it a necessary addition to your maternity wardrobe. These ultra-feminine and playful skirts are a great way to show off your baby bump in style!

5. Peasant tops. Catch the Bohemian wave this season and enjoy a splash of color with a peasant top. Maternity peasant tops and blouses are designed with extra fabric and tend to flare out at the waist and sleeves. This is a great cut for moms-to-be, and can be especially flattering if you've gained some weight.

Staying cool and comfortable in the heat can be a challenge in itself, and you can multiply the effects of the heat by ten when you're pregnant. Pick up any of these stylish summer must-haves so you can enjoy the best of the season!

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.

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.
