Styling Tips by Season: Dress for the Weather, Slay in Every Setting
Weddings happen year-round, and your wardrobe should flex with the calendar. Here’s how I break it down when helping friends or readers find the perfect outfit.
Spring
Spring weddings call for soft pastels, florals, and flowing fabrics. Think simple glowns with romantic drapes or lace accents. Add strappy heels and light accessories for garden or outdoor ceremonies.
Summer
Breathable is best. Sleeveless styles, breezy maxis, and off-shoulder details shine here. Summer is where casual meets classy, especially for beach or poolside venues.
Fall
This is my favorite season for styling. Rich tones like burgundy, emerald, and navy make a statement. Layer with shawls or structured blazers to balance warmth and style.
Winter
Bring the drama! Velvet, satin, sequins—go all in. Opt for longer sleeves and jewel tones, and don’t forget boots or closed-toe pumps for chilly receptions.

How to Choose the Right Dress for You
You’ve got the looks—now let’s refine the decision-making process. I always recommend asking:
1. What’s the dress code?
Semiformal? Casual? Formal? Always start here.
2. What season is the wedding in?
You want your dress to match the temperature and aesthetic.
3. Will there be a party or reception?
If dancing is involved, test movement in your dress before you commit.
4. Do I feel confident in this?
Don’t settle. You want a dress that makes you feel like a guest of honor.
5. Do the accessories complement or compete?
Simple glowns are elevated with the right clutch, heels, and jewelry.
