21 Summer Wedding Suits for Guests That Perfectly Fit the Dress Code

While wedding invitations generally come with a flood of excitement, there's also an unwritten list of to-dos every guest has to take care of before the big day. And when it comes to summer celebrations, deciding what to wear is one of the biggest tasks of all. Summer wedding suits don't just have to look good, they have to feel comfortable too—and that can be easier said than done when hot weather is involved. That's why we're sharing our top tips for buying men's summer wedding attire, including what to look for, where to shop, and our favorite styles you can order online. 

What to Look for in a Summer Wedding Suit

Suit criteria changes depending on the dress code, venue, and time of day an event is taking place. That said, there's one thing to pay attention to no matter what: the fabric. Assuming the weather will be warm, lighter materials like linen and cotton are both great options. You also don't have to throw the idea of wearing wool out the window—simply opt for a lighter weight version or a wool that's blended with silk or linen. Seersucker suits are another great option, thanks to the material's durable, lightweight, and crease-resistant qualities. 

Summer weddings are also a great opportunity to play around with colors and prints. Bright shades of blue are a popular choice for guests, but don't be afraid to explore other options like light greens, pinks, and purples. If you'd rather keep things subtle, opt for slightly less saturated shades like pastels or skip the colorful suit altogether and play up your outfit with a fun necktie or bow tie instead. It's also good to keep in mind that very formal events (think: a formal evening wedding) typically call for darker hues. If that's the case, you might want to skip the playful prints and go with a classic charcoal gray, navy blue, or black suit. 

Where to Buy Summer Wedding Suits

Shopping in person at your local suit store comes with some great perks. You get a personalized experience from start to finish, including help with finding the right style and sizing. Plenty of retailers also offer in-store alterations so you can get everything done in one place. That said, there are lots of great retailers online nowadays offering everything from custom-tailored tuxedos to trendy three-piece suit rentals. No matter your style or budget, there's something out there for everyone. To help you get started, here are three of our favorite men's formalwear websites: 

• Indochino: Indochino offers a made-to-measure experience from the comfort of your couch. Simply choose a suit from the site's collection, customize the details, upload your measurements, and you're good to go.
