Top Summer Fashion Trends to Watch in 2025
If There’s One Word to Describe Summer 2025 Fashion Trends, It’s “Comebacks”
This summer, fashion is all about returns. Many past styles are making their way back into the spotlight – some of which we never expected to see again. From bold colour variations and eye-catching accessories to playful layering, the summer 2025 fashion scene in Great Britain is defined by its dynamic mix of the old and the new.
The Return of Pastel Palettes
The early 2010s were dominated by soft pastel tones. In 2025, pastels are making a comeback – though they won’t be the only colours you see in shop windows. They’ll be sharing the spotlight with earthy tones and vibrant brights, but there’s no doubt pastels will take centre stage in many wardrobes.
Lightweight Layers for Breezy Comfort
European summers are cooler than in many other parts of the world, which means we can’t say goodbye to outerwear completely. But that’s not a bad thing – especially this year, as lightweight layers are back in style. Think airy cardigans, fine knits, crisp shirts, and light denim jackets. These pieces add depth, texture, and colour to your outfit without making you overheat.
Statement Accessories Making a Comeback
Many thought this trend was left behind in the 2010s, never to return. But fashion is always cyclical, and statement accessories are back – and bolder than ever. If you didn’t toss your chunky necklaces, you’re in luck, because the chunkier, the better. If necklaces aren’t quite your thing, you can still embrace the trend with standout earrings or oversized rings. It’s not about being subtle – the goal is to stand out.
Colour Trends Dominating Summer 2025 Fashion
One thing we love about the colour trends for summer 2025 is just how varied they are. This makes it easy for everyone to choose their favourites – or those that suit their skin tone best – without missing a beat on what’s trending. Here, we’ll break down the colours that are in this season, and how you can work them into your wardrobe.
Earthy Tones vs Vibrant Brights
British summer fashion trends in 2025 is all about a balance between earthy tones and vibrant brights. We recommend using one palette per outfit – either go full earthy or full bright – to keep things cohesive. That said, feel free to mix and match if that’s more your style. You can also pair a bold piece with crisp white basics to maintain that fresh, light summer look.
Our LAYLA Beige Embroidered Shirt is the perfect way to bring earthy tones into your outfit without it feeling too heavy or autumnal. On the other hand, the LAYLA Rust Grouse adds just the right splash of vibrancy to reflect the lively, sun-soaked feel of summer.
Coordinating With Nature-Inspired Prints
Beyond colour, nature-inspired prints are also a standout trend this summer. At Hartwell, we’re big fans of these prints – they give us the chance to highlight the beauty of the natural world and iconic elements of the British countryside, whether it’s through pheasant motifs, equestrian themes or floral patterns.
These work especially well if you prefer earthy, pastel or neutral tones, as the print itself becomes the standout feature, adding depth and interest to your outfit. You could go for a printed bottom, like our OLIVIA Navy Snaffle Skirt, or a printed top such as the EVIE Colourful Pheasants – both are brilliant ways to work this trend into your everyday looks.
Styling Tips for Effortless Day-to-Night Outfits
The British summer often brings unpredictable weather shifts throughout the day. You might leave the house feeling perfectly fine in a light blouse and a skirt, but by late afternoon the cool breeze starts to set in. There’s no need to panic, though – with our tips, you’ll be able to create styling trends, functional outfits that work from morning to evening.
From the Office to Happy Hour
These occasions usually go one of two ways: either your office has freezing air con, and you’re roasting the moment you step outside for lunch, or the temperature is mild, and you feel the breeze as soon as the afternoon sets in. In either case, it’s key to put together outfits that keep you comfortable and at the right temperature all day long.
Our RUBY Classic Cotton Trousers are ideal for office wear – they’re smart but not as warm as our lovely velvet jeans. We’ve also restocked our ROSIE Skinny Jeans which add a formal yet chic touch to your look.
As for tops, our HILLA White Luxury Blouse and MALU Frill Neck Blouse are great options if you don’t want your neckline completely exposed. These pieces are made from breathable fabrics, so you’ll stay cool while still feeling covered.
From Picnic to Patio Party – No Change Required
Summer isn’t all about work; it’s also about those iconic weekends spent enjoying time with friends and loved ones throughout the day. If you’re heading out early and won’t have time to stop home for an outfit change, we’ve got just what you need.
Our HOLLY Blue Snaffle, ALINA Colourful Flowers, and SAMANTHA Blue Dress are all perfect choices. We know dresses might not be your first thought for a picnic, but ours are all cut below the knee, so you can wear them comfortably and sit down without worry.
If you prefer shorts, you can still dress them up with one of our stylish tops. The CHLOE Linen Pheasants Shirt and ISABELLA White Embroidery are super breathable and pair beautifully with linen or denim shorts – they’ll instantly elevate any bottom you choose.
Add Functional Accessories Without Overheating
The must-have accessory for summer 2025? Silk scarves. As we’ve mentioned, earthy tones and pastels are leading the way this season, so adding a pop of colour is essential to reflect the vibrant side of summer. Our SABRINA Italian Silk Scarves in green and peach are the perfect way to do this, without clashing with the rest of your outfit.
Scarves are also handy for protecting yourself from cold air con. Many people experience sore throats or allergy-like reactions when exposed to direct air from fans or cooling systems. With our silky scarves, you can shield your neck from the chill, stay stylish, and avoid overheating all at once.
