Between the luxurious gowns, Becky Armstrong gave us a 101 in styling summer suits during her stint at Cannes Film Festival 2025. With a stamp of approval from the Thai actress, we're thinking this 2025 fashion trend has the potential to carry on into the summer.

Blazers and pants are probably not on your mind as the temperatures heat up. You might want to reconsider that. Summer suits can give you that classically chic edge this season, so you not only look but also stay cool.

Popularized by celebrity street style, the suit trend has taken the formal and office wear staple and given it a more modern, casual look. The beauty of the trend is that it allows everyone to re-interpret the classic suit and put their own unique creative touch on it, whether that’s giving it the oversized treatment like Hailey Bieber, going for quirky combinations of vintage pieces like Bella Hadid, or applying an aesthetic that fits your vibe.

Fittingly, its versatility is the key to wearing suits for summer. You can modify the suit as you need and find the best fit for you. Here are six ways to style summer suits:

1. Big Sleeves, Fitted Shorts

One of the biggest trends from New York Fashion Week Spring-Summer 2025 was contrast in tailoring, with oversized tops juxtaposing tiny fitted shorts. Kicking off the trend, Becky Armstrong brought the look to Cannes Film Festival 2025, giving it an ultra luxe feel. (ICYMI: Her co-star Freen also did a take on suiting at the Met Gala 2025, so there's plenty of inspo to go around.)

2. The Corset and Suit

With the weather getting hotter, you might want to tone down the layers. This trend allows you to do just that, while also adding an extra element of style to the suit. The corset itself is also super trendy at the moment, so it’s a double win.

3. Just the Blazer

You can always skip a layer too. Try going with just the blazer and nothing underneath. You’ll feel cool — literally and figuratively.

On the other hand, if you'd like to keep it more conservative, swap your classic button-up shirt for a stylish blouse beneath your blazer. These can still be breezy and cool if you opt for the right silhouette and fabric, like billowy linen. If it has a decorative element, like a bow, then it adds a flair to the suit as well.

5. The Matching Set

Given the heat, you might become emotionally attached to your athletic sets in the summer like me. Maybe you can find comfort in a matching suit set for days when you’ll have to dress up a bit more. With plazacore on the rise, there are plenty of classic chic styles. Or you can go for a bold, modern look with a bright color and a fun fabric.

7. The Skirt-Over-Pants Suit

If you’re looking to keep the style modest or really get into the trends, up the ante with a skirt layered over pants. This is a super easy way to take on the trend without looking like Ashley Tisdale in the 2000s.

Pro Tip: Summer Colors

You can still stick to the traditional suit if that's more your speed. Just consider giving it an update with some summer hues. You can go for a bold, bright color like Barbie pink or stick to the neutrals with an earthy taupe or bright tan.

The best part of this trend is that you probably already have some pieces of a suit in your closet that you can style for the summer. When thrifting for suits, you can also find some great gems. On the off chance that you don’t have something readily available, we’ve got you covered.
