There’s something reassuring about a trench coat: the rustle of the fabric, the smart silhouette, the little flap over the shoulder that looks like it belongs in a film. Living in the UK, I’ve treated the trench as essential outerwear—not just for its classic good looks, but because it can actually cope with our famously changeable weather, tuck into a weekend bag and make me feel instantly put together. After years of testing different cuts and materials, here’s how I choose a trench that survives British rain, flatters my shape and packs down without wrinkling into a suitcase.
What I look for in a rain-ready trench
Not all trenches are created equal when it comes to weatherproofing. For me, the ideal rain trench has a few non-negotiables:
Water-resistant fabric: Traditional gabardine (a tightly woven cotton) has a natural water-shedding quality and ages beautifully. Modern trenches may use coated cotton or lightweight technical fabrics (think polyester blends or nylon with DWR finish). Both work—gabardine feels more luxe; technical fabrics are lighter and pack better.Good lining: A fully lined or partially lined coat hangs better and prevents the outer fabric from clinging when damp. A cotton or viscose lining is breathable—important for layered dressing.Sealed seams or taped stitching: In heavier rain you’ll appreciate a coat with reinforced seams, even if it’s not a full-on raincoat.Classic features that block weather: Storm flap, deep collar, belted waist and adjustable cuffs help keep wind and drizzle out.Fit that flatters—what works for most shapes
The trench is one of the few garments that can truly flatter a wide range of bodies if you pick the right cut and play with styling. Here’s what I advise when trying one on:
Define the waist: Even if you prefer a looser fit, cinching the belt transforms a shapeless drape into something polished. For apple shapes, I recommend a belted trench worn slightly open so the belt sits just above the natural waist rather than compressing the midriff.Choose the right length: Knee-length is universally flattering and practical for rainy British days. Midi trenches (mid-calf) are elegant but can overwhelm petite frames unless balanced with heels. Cropped trenches are great for petite or curvy hips because they highlight the waist.Sleeve and shoulder fit: The trench should fit comfortably across the back and shoulders—there should be room for a jumper underneath without bulk. Raglan sleeves or set-in sleeves with a bit of room are both fine.Pay attention to proportions: If you have a shorter torso, avoid a too-long trench that makes you look swallowed. Taller frames can carry longer lengths beautifully.Materials and construction: balancing weatherproofing and packability
For a trench that will live in my travel bag and handle UK drizzle, I tend to favour two options:
Coated cotton/gabardine: These are classic, breathable and look better with age. They’re reasonably packable—roll carefully and they recover nicely from creases. Look for a mid-weight gabardine with a DWR (durable water repellent) finish for extra protection.Technical nylon or polyester blends: These are lightweight, dry quickly and pack extremely small. The downside is they can feel less structured and sometimes creak. They’re ideal if you need to fold your trench into a weekend bag or compress it into a carry-on pocket.Construction details to check:
Top-stitched seams: These add durability and keep the shape.Quality hardware: Buttons and buckles should be sturdy. A double-breasted front with hidden snaps adds wind protection.Detachable liners: If you want a trench you can wear year-round, a removable liner gives you warmth when needed without bulk when packing.How I pack a trench so it survives the journey
Packing a trench for a weekend away without creases is possible with a little technique. Here’s my go-to method:
Turn the coat inside out and lay it flat on the bed.Fold each sleeve diagonally across the back so they cross at the middle.Fold the coat in half vertically (collar to hem), then roll tightly from the hem up to the collar.Place the rolled trench in the middle of your suitcase and pack softer items like sweaters around it to cushion and keep it in place.If I’m short on space I’ll wear the trench on the plane or drape it over my lap—airlines’ coat hooks in the cabin can help reduce wrinkling.
Styling tips that make a trench feel modern
I love how a trench can transform everything from jeans and trainers to a slip dress. A few styling ideas I keep returning to:
Belted over knitwear: A fitted sweater and tapered trousers with a belted trench creates a chic, hourglass silhouette—great for school runs or meetings.Layered open: Wearing the coat open with the belt tied loosely at the back gives a relaxed, Parisian vibe.With casual separates: Throw it over a hoodie and tailored joggers to elevate a sporty look without trying too hard.Dress it up: For evening, swap the belt for a leather one and add heeled boots—instantly polished.Brands and models I've tested
Over the years I’ve tried many trenches; here are a few reliable ones I keep recommending for British weather and travel:
| Model | Why I like it | Best for |
| Burberry Kensington | Classic gabardine, impeccable cut, great lining and weather resistance | Investment piece for a timeless closet |
| Aquascutum Corby | Traditional tailoring, slightly roomier fit and excellent rain performance | Those who want a classic British brand with a forgiving silhouette |
| Uniqlo BlockTech Trench | Affordable, lightweight, highly packable and surprisingly weatherproof | Travelers and everyday commuters on a budget |
| Rains Long Trench | Technical fabric that’s sleek, waterproof and very packable | Minimalist, practical waterproof option |
Care tips to make your trench last
To keep a trench in top shape:
Brush off dirt and let it dry fully before storing.Follow the manufacturer's washing instructions—some trenches are hand-wash only or require specialist cleaning.Refresh DWR coating periodically with a spray-on water repellent if water starts to bead differently.Store on a good hanger to maintain shape; avoid cramped wardrobes where the lapels get crushed.Choosing a trench that survives British rain, flatters your shape and tucks into a weekend bag is about prioritising the right fabric, a flattering cut and smart construction. Whether you invest in a heritage gabardine or opt for a technical, packable version, there’s a trench that will become your reliable go-to—one that makes rainy days feel a little more elegant and travel a lot less fraught.
