Summer weddings in 2025 are all about celebrating love in the sunshine — but dressing for heat, humidity, and varying dress codes can feel tricky. Whether the invite says "beach formal," "garden party," or "cocktail," the key is breathable fabrics, light colors, and effortless elegance. This guide covers everything: trends like floral prints and pastel suits, do's and don'ts, and outfit ideas for women and men that balance comfort, style, and respect for the occasion.

General Rules for Summer Wedding Guests in 2025
Before diving into outfits, remember the basics:
- Avoid white, ivory, or anything bridal — let the couple shine.
- Check the dress code — "summer formal" means lighter fabrics, not casual.
- Prioritize breathable materials — linen, cotton, chiffon, lightweight silk.
- Colors — Pastels (butter yellow, powder blue, blush), bright florals, earth tones. Bold pops like coral or emerald for fun venues.
- Shoes — Wedges or block heels for grass; comfortable flats or sandals for beach.
- Accessories — Minimal: straw hats, delicate jewelry, small clutches.
2025 trends from Who What Wear and Brides emphasize polka dots, drop waists, ruffles, and butter yellow — but always adapt to formality.
