The Best Transition Style: Red From Summer to Fall 2025

In just a few days, we’ll officially step into Fall 2025. But honestly, who’s already in the mood for cashmere and faux-fur coats? Not quite yet. Still, now is the perfect time to scan your summer wardrobe and decide which pieces deserve a stylish upgrade for the transition from summer to fall. And for me, the Best Transition Style this year is all about one unexpected hero: a simple red dress.

From Summer to Fall 2025: The Red COS Dress

Back in June, COS gifted me a red cotton dress. It became my travel companion everywhere: Vienna, Madrid, Puglia, Hamburg, and back home to France. After countless miles, I know it’s not going into storage anytime soon. In fact, this dress will carry me through September and possibly even October.

The real question is: how do you style a red summer dress for Fall 2025? Here’s my take, guided by three key seasonal trends.

1. Lazy Elegance

Dress, Trench Coat, Long Sleeve T-shirt and Shoes from COS

Lazy Elegance is one of Fall 2025’s most refreshing trends. It rebels against the flawless, hyper-curated looks of TikTok and embraces layering, mismatched colours, and an effortless kind of chic.

Style your red dress with a T-shirt underneath, striped for playfulness, or in a surprising shade like deep green or lilac. Throw on an oversized trench coat and finish the look with statement shoes, maybe with socks. The result? Perfectly undone.

2. Mocha Brown

Leather Coat, Dress, Hat, Cashmere T-Shirt and Mule from COS

Mocha Brown was an obsession last fall and winter, and it’s making a strong comeback in 2025. Pair your red dress with a brown leather jacket and a brown fisherman’s hat. Complete the outfit with a chic faux fur mule for the ultimate mix of comfort and style.

This is Lazy Elegance at its finest: nonchalant, cosy, but still striking.

3. Tailoring

Dress, Blazer, Chocker and Leather Woven Loafers from COS

The blazer never left us, but this fall it comes with exaggerated proportions and sharp shoulders. Think pinstripe or black tailoring for extra attitude.

Wear your red dress with a boxy blazer and heels for a polished night out, or swap the heels for a leather woven loafers for a playful twist.

Et voilà: My Best Transition Style for 2025

Who knew a simple red cotton dress could unlock so many looks? With a few clever layers, it’s the perfect piece to take you from summer to fall.

So yes, my Best Transition Style 2025 is all about a red dress. Will you try it too?
