It's summer party season, and there are plenty of new warm-weather fashions to try. Style expert Chassie Post stopped by TODAY Thursday to share some fresh trends the entire family will love.
1. Gingham and camo
Post likes to call these trends the new classics: gingham is always fresh for summer and Army-inspired patterns, like camo and olive green, are must-have staples. These trends work perfectly on everyone — men, women, boys, girls and people of all ages and sizes.

For him:
This handsome dad is rocking a classic navy-and-white gingham shirt by J Crew, which can be mixed with any bottoms in his wardrobe for the perfect pick-me-up. This look is kept business-casual with the addition of a slim-stretch chinos in olive green. The slim and slightly cropped cut is a sleek, polished and a cool take on a classic pant. The look is finished off with great brown leather brogues worn with no socks for a little flash of ankle.

For little him:
For a very stylish son, this larger scale neon orange gingham will be tops. We paired his shirt with another take on the army pant: blue camo joggers. His look is finished off with one of the biggest shoe trends of the season, the pool slide sandal.

3. Animals and stripes
Whether they're hitting the beach or pool, animals and stripes are the way to do so in style.

For little him:
From sharks to dinosaurs, critters are a big trend in beachwear this season. Pair the swim trunks with a French Breton-stripe T-shirt and a navy rash guard with white seam detail for a fresh look. Also, these water shoes by Native Shoes are rubber versions of sneakers that are perfect for the ocean or any puddles.

Critters aren’t just for kids! A stylish dad can wear a more mild-mannered animal on his navy beach trunks: little turquoise seahorses. We added a coordinated mini stripe (another big trend) on a Polo shirt and Haviana’s waterproof version of the espadrille.
