Wedding season is here. Whether you're the groom, a groomsman, or a guest trying to figure out what "cocktail attire" actually means, this guide breaks down exactly what to wear — and what to skip — for every spring wedding dress code.

Spring weddings come with their own set of style rules. The weather is unpredictable, the venues range from garden ceremonies to ballrooms, and the dress codes can be anything from "black tie optional" to "garden party casual." Getting it right means understanding the occasion first, then building your outfit around it.

Step one: decode the dress code

Every wedding invitation tells you what to wear — you just have to know how to read it. Here's a quick breakdown of the most common dress codes and what they actually mean for men.

  • Black tie: Tuxedo or formal dark suit with a white dress shirt and bow tie. This is the most formal option.
  • Black tie optional: A sharp 3-piece suit in navy, charcoal, or black. No tuxedo required, but dress to impress.
  • Cocktail attire: The most common spring wedding dress code. A 2-piece or 3-piece suit in a spring color. Ties optional.
  • Garden / casual: Sport coat with dress slacks, or a lightweight suit in a lighter color. Relaxed but still polished.

Spring color guide: what works and what to avoid

Spring weddings call for lighter, fresher colors than the deep navy and charcoal of winter. Think medium blue, slate, sage green, tan, light grey, and warm brown. These tones feel seasonally appropriate without being too casual for a formal occasion.

Avoid wearing all-white (reserved for the bride) or all-black unless the dress code specifically calls for it. Deep burgundy and forest green are fine in small doses — as an accent tie or pocket square — but as a full suit they risk feeling too heavy for a spring ceremony.

Quick rule: When in doubt, navy is always the right call. It's formal enough for any dress code, fresh enough for spring, and works with almost any shirt and shoe combination you already own.

The best looks by occasion

1. The formal ceremony — 3-piece suit

For black tie optional or upscale cocktail weddings, a 3-piece suit is your strongest move. The vest elevates the look instantly and keeps you looking sharp even when the jacket comes off at the reception. Pair with a crisp white dress shirt, a silk tie, and oxford shoes. The Stacy Adams 3-piece hybrid in a bold color is a standout choice for guests who want to make an impression without upstaging the wedding party.

2. The cocktail wedding — slim 2-piece suit

Cocktail attire is where most men have the most freedom. A well-fitted slim 2-piece in medium blue, light grey, or tan hits the sweet spot between formal and fresh. Skip the tie if the venue is outdoors, and opt for loafers or clean leather dress shoes. The Vinci slim fit with adjustable waistband is ideal here — the stretch fabric means you'll be comfortable from the ceremony to the last dance.

3. The garden or outdoor wedding — sport coat & slacks

For relaxed garden ceremonies or venues with a "dressy casual" code, skip the full suit and go with a patterned sport coat over dress slacks and a button-down. A linen or lightweight blazer in a neutral keeps you cool as temperatures rise through the afternoon. This look also gives you flexibility — dress it up with a pocket square, or keep it relaxed with no tie. Browse CCO's men's sport coats collection for spring-ready options.

4. The groom or groomsman — go all in with a 3-piece pinstripe

If you're part of the wedding party and want a coordinated look that still has personality, a pinstripe 3-piece is a sophisticated choice that photographs exceptionally well. The Tazio 3-piece executive pinstripe with its 6-button vest brings a timeless formality without crossing into stuffy territory. Pair with a white spread-collar shirt and a complementary tie in the wedding's accent color.

The finishing touches

Shoes. For formal ceremonies, go with oxfords or derbies in black or tan. For garden or outdoor weddings, a clean loafer is both practical and stylish — and far easier on grass than dress shoes with narrow heels.

Pocket square. The single easiest way to elevate any suit. A white or light-colored pocket square in a simple fold keeps things classic. Match it loosely to the wedding's color palette if you know it — but never match it exactly to your tie.

Fit above everything. A $150 suit that fits perfectly will always look better than a $500 suit that doesn't. When ordering, size for your jacket shoulders first — pants can be hemmed, but shoulder alterations are costly. CCO's size guides make it easy to get the right fit from the first order.

The bottom line

Spring weddings reward men who put in a little thought. Know your dress code, lean into lighter spring colors, and invest in a suit that actually fits. Whether you're walking down the aisle or sitting in the third row, CCO Menswear has everything you need to show up looking like you belong there.
