Rainy days in the UK are unavoidable—so why not dress smartly for them? From water-resistant fabrics to clever layering techniques and brands that combine performance with polished aesthetics, this guide walks you through everything you need to stay dry and stylish.
Whether you’re commuting, walking the dog, or heading to dinner, here’s how to dress for wet weather—with the right materials, silhouettes, and style tips. And with Tellar.co.uk, you’ll always know your exact size for each item, no matter the brand.
Best Materials for Rainy Days
Rainy weather dressing starts with the right fabrics. Here are the top choices:
1. Gore-Tex and Technical Membranes
Used in high-performance outerwear, Gore-Tex is waterproof, windproof, and breathable. Look for seam-sealed construction for maximum dryness.
2. Waxed Cotton
Popular in British outerwear, waxed cotton has a classic look and natural water resistance. It’s heavier than synthetics but perfect for trench coats or field jackets.
3. Nylon and Polyester with DWR Coating
Many everyday rain jackets use nylon or polyester treated with DWR (durable water repellent). Lightweight and packable, they’re ideal for city use.
4. PU-Coated Fabrics
Polyurethane-coated materials offer solid water resistance, often used in rain macs and minimalist outer layers. Slightly less breathable, but effective for short outings.
5. Merino Wool (for layering)
Surprisingly effective in rain, Merino wool keeps you warm even when damp and regulates temperature. Ideal as a base or mid-layer under waterproofs.
Layering Smartly: What to Wear Under Your Rain Jacket
Even the best waterproof shell is only part of the picture. Focus on layering with moisture-wicking, breathable materials underneath.
-
Top Layer: Technical shell, trench or waxed jacket
-
Mid Layer: Merino jumper or performance fleece
-
Base Layer: Bamboo or polyester blend top (not cotton, which soaks)
-
Bottoms: Water-repellent trousers or coated jeans

Best Types of Clothing for Rainy Days
1. Rain Trench Coats
A classic rainy-day staple, trench coats work across office and casual wardrobes. Look for water-resistant fabrics and belt ties to define your silhouette.
2. Packable Rain Jackets
For on-the-go practicality, choose jackets that fold into compact pouches. These are usually ultra-light and wind-resistant, perfect for summer showers.
3. Wax Jackets & Utility Styles
Brands like Barbour-inspired fits blend country heritage with city practicality. Look for handwarmer pockets, storm flaps, and detachable hoods.
4. Waterproof Trousers and Wide-Leg Options
In wetter months, avoid dragging hems. Choose cropped waterproof trousers or wide-leg styles with a shorter inseam.
5. Chunky Boots or Rubber Chelsea Boots
Pair your outfit with waterproof footwear—Chelsea boots in rubber or treated leather are rainproof without looking too rugged.
