What to wear in 15–20 °C weather
Choose a breathable base and carry one light layer. Trousers, denim, midi skirts, tees, shirts, and loafers all work; the jacket is for shade, wind, and the evening.

Outfit ideas
Pick the direction that feels like you. Each one follows the practical advice above, but the level of polish and personality changes. Swap colors and pieces for what you already own, and open a look to read its full style guide.
Formula 01
Preppy
Collegiate, clean-cut charm
Polo shirt, tailored shorts, cable-knit over the shoulders, and loafers.
- Why it works
- Neat layers and familiar sportswear references balance comfort with visible polish.
- Choose another look if
- The plan is highly formal or the temperature makes layered knits uncomfortable.
Formula 02
Smart Casual
Polished, without a suit
Silk blouse, dark straight jeans, blazer, and loafers.
- Why it works
- The tailored layer adds structure without pushing the outfit into full formalwear.
- Choose another look if
- The setting is strictly formal or your day is too active for tailored layers.
Formula 03
Romantic
Soft, feminine, dreamy
Floral midi dress, cardigan with pearl buttons, and ballet flats.
- Why it works
- Soft shapes and delicate details create a dressed-up look without severe tailoring.
- Choose another look if
- You prefer sharper lines or the weather makes light fabrics and delicate shoes risky.
→ 03 / What to skip
Mistakes to avoid
- Dressing for the midday high when you leave early and return late.
- Choosing synthetic layers that trap heat as soon as the sun appears.
- Taking a bulky jacket instead of a layer that fits in your bag.
