The small details that keep you cool, comfortable, and polished when the city hits 30°C.
When dressing for a city summer, we tend to spend all our energy focusing on the big decisions—finding the perfect linen trousers, hunting down breathable cotton shirts, or figuring out which fabrics won’t betray us the second we descend onto the Central line.
But once you’ve got the foundations sorted, it’s often the smallest details that determine whether you spend the day feeling comfortably put-together or quietly irritated by 3pm.
In a London heatwave, the wrong accessories become impossible to ignore. Heavy bags stick to your body, sunglasses slide down your nose the second humidity arrives, and wearing your hair down starts to feel suspiciously similar to walking around with a scarf wrapped around your neck.
This isn’t beach holiday dressing. It’s London heatwave dressing. The kind where you’re moving between overheated Tube platforms, office air conditioning, and after work drinks on a central London pavement. The goal isn’t just to look chic and put together, it’s to minimise friction, maximise airflow, and make the city (and London heatwaves) feel slightly more bearable.
Here are some small accessories that I think make all the difference.
1. Sunglasses: The Anti-Slip Framework
Finding sunglasses that survive a humid London afternoon is less about trends and more about weight and comfort.
Heavy acetate frames might look incredibly chic, but once your skin starts to sweat, they can become frustratingly slippery. Nobody wants to spend an entire day constantly pushing their sunglasses back up their nose. I also find any material touching my face makes me feel warm, and so want as little contact with the glasses frame as possible.
For heatwave dressing, lighter frames are your friend. Wire styles with adjustable silicone nose pads offer extra grip, while keyhole bridge designs create a small air gap across the nose, reducing that sticky feeling that often develops in high humidity.
The System Choice
Look for lightweight frames that sit comfortably without clinging to your face.
2. Hair Accessories: Get It Off Your Neck
Few things become more irritating in a heatwave than hair plastered to the back of your neck.
Fortunately, some of the most useful summer hair accessories also happen to be the easiest ways to add personality to an outfit.
The Matte Claw Clip
Large claw clips remain elite summer hardware. They lift the bulk of your hair away from your neck without pulling everything tightly against your scalp, allowing far more airflow than a slicked-back bun.
The Linen Scrunchie
For softer styles, oversized linen or silk scrunchies distribute pressure more evenly than traditional elastics and make even a simple low bun feel intentional.
The French Hair Pin
Elegant and lightweight, French hair pins create loose twists that keep your hair off your skin without feeling overly structured.
The System Choice
Oversized claw clips, soft linen scrunchies, and simple hair pins that prioritise comfort over perfection.
I love the claw clips from Accessorize, they’re so stylish and are priced well. You can browse their range here.
3. Bags: Minimise Contact
The problem with many summer bags isn’t weight – it’s where they sit.
Crossbody straps can become surprisingly uncomfortable during long walks, trapping heat and creating exactly the sort of friction you’re trying to avoid. Heavy leather totes may look beautiful but can quickly feel oppressive when temperatures climb.
The answer isn’t necessarily abandoning style. It’s simply choosing bags that allow your body a little breathing room.
The Raffia Shoulder Bag
Lightweight and breathable, woven raffia bags feel unmistakably summer-coded without sticking to bare skin.
The Structured Basket
Short top handles keep the bag away from your torso altogether, making baskets one of the most comfortable warm-weather options around.
The Cotton Net Bag
Perfect for park days, markets, and casual weekends, net bags pack flat, weigh almost nothing, and allow plenty of airflow.
The System Choice
Lightweight woven bags and structured top-handle styles that minimise unnecessary contact.
I think Accessorize have some stylish raffia bags and Arket have some stylish tote bags.
4. Portable Cooling: Tiny Tools That Earn Their Space
By the third day of a heatwave, you’ll probably care less about statement jewellery and more about the small objects you’ve somehow become emotionally attached to.
The Folding Hand Fan
Quiet, elegant, and requiring absolutely no charging, a folding fan offers instant relief when the air feels completely still. There’s a reason they’ve survived centuries.
The Rechargeable Mini Fan
Modern portable fans have come a long way. Compact versions are lightweight, surprisingly quiet, and ideal for overheated commutes or stuffy offices.
The System Choice
Slim fans that disappear into your bag but save your sanity when the city feels stagnant.
Brand Recommendations: Muji and John Lewis.
5. Water Bottles: Hydration That Doesn’t Feel Like an Afterthought
One of the simplest luxuries during a heatwave is drinking genuinely cold water.
The best water bottles aren’t necessarily the biggest or most engineered, they’re the ones you’ll actually carry every day.
The Insulated Bottle
Keeping water cold for hours turns hydration from a chore into one of the small pleasures that makes city life considerably more pleasant.
The Slim Everyday Bottle
For smaller bags and everyday commutes, slimmer profiles are often more practical than giant tumblers that dominate your entire tote.
The System Choice
Lightweight insulated bottles that fit your routine rather than disrupting it.
Brand Recommendations: Yeti, Owala, Chilly’s, Stanley, SHO, Ello.
Read my review of the Ello Pop & Fill Bottle, the Stanley Iceflow or for something a little more portable, my review of the SHO Newt bottle.
6. Hats: Shade Without the Sweat
A good summer hat should feel less like a costume and more like portable shade.
Heavy baseball caps and thick fabrics can trap heat against your scalp, but lightweight natural fibres allow warm air to escape while protecting your face from direct sun.
The Raffia Bucket Hat
Packable and breathable, raffia hats strike the balance between practicality and style.
The Linen Cap
Unstructured linen caps offer sun protection without turning your head into an oven.
The System Choice
Natural fibres and open weaves that provide shade without sacrificing airflow.
Final Thoughts: Comfort Lives in the Small Details
Surviving a London heatwave with your style intact isn’t about reinventing your wardrobe. More often, it’s the little things that matter most.
The sunglasses that stay put. The claw clip that gets your hair off your neck. The bag that doesn’t stick to your side. The water bottle you’ve become weirdly protective of.
Individually, none of these things seem particularly significant. But together, they create something surprisingly valuable: a summer wardrobe that works with the city rather than against it.
Because in London, dressing for a heatwave isn’t about pretending you’re on holiday.
It’s about staying comfortable enough to enjoy the city while still looking like yourself.
