As the temperatures rise and the days stretch longer, it’s time to refresh your wardrobe with key summer staples that are both stylish and functional. Whether you're heading to rooftop drinks, working from a café, or soaking up sun on the coast, your wardrobe should work hard and look effortless.
Below, we break down the essential summer pieces every wardrobe needs in 2025, plus how to make sure everything fits you perfectly—with help from Tellar.co.uk, the UK’s leading free clothes sizing tool.
1. The White Linen Shirt
Crisp, breathable, and endlessly versatile. The white linen shirt is the ultimate summer chameleon—tuck it into tailored shorts, layer it over a bikini, or pair it with wide-leg trousers.
Look for:
-
100% linen or a linen-cotton blend
-
Oversized fit or belted waist for structure
-
Side slits or curved hems for movement
📍 Available in COS, Uniqlo, Mango and Massimo Dutti—just check your fit on Tellar.co.uk
2. Tailored Shorts
Say goodbye to denim cut-offs—tailored shorts are clean, elegant, and wearable from brunch to business casual. Choose a slightly longer length and high waist for the most flattering effect.
Perfect in:
-
Neutral tones: cream, camel, olive
-
Fabrics like linen, cotton twill, or crepe
-
Paperbag waists or pleated fronts for extra style points
🧵 Unsure what size fits you in Reiss vs. H&M? Use Tellar.co.uk to find your match instantly.
3. The Everyday Midi Dress
You need at least one midi dress that works for everything—running errands, last-minute dinner plans, garden parties. Flowy silhouettes, breathable fabrics, and flattering cuts are key.
This season’s trends include:
-
Tiered skirts or wrap styles
-
Puff sleeves or open backs
-
Earthy tones, pastel shades, and subtle florals
Brands like & Other Stories, Whistles and Nobody’s Child are doing these beautifully—just make sure it fits properly with a quick check on Tellar.co.uk.
4. Breathable Wide-Leg Trousers
Easy, elegant and relaxed—wide-leg trousers are a warm-weather must-have. Pair with a crop top, tank or tucked-in tee. They elongate the body and keep you cool.
Opt for:
-
Lightweight cotton or linen blends
-
High-rise waist and pockets
-
Neutrals like stone, white, navy, sage
📐 Proportions matter with wide-leg trousers—use Tellar.co.uk to ensure a tailored waist without needing a belt.
5. A Great-Fitting Tank or Ribbed Vest
Minimalism never looked so good. Ribbed tanks and high-quality cotton vests are this summer’s layering hero—tucked into jeans, under a shirt, or with maxi skirts.
Look for:
-
Square neck or racerback
-
Soft ribbed cotton or organic stretch
-
Neutral colours: black, white, stone, ecru
From Arket to Zara, sizing varies dramatically—especially around the bust. Tellar.co.uk can tell you exactly what size to buy in each brand.
6. An Oversized Shirt Dress
A shirt dress is the ultimate throw-on-and-go piece. Structured enough to look polished, but relaxed enough to wear on hot days.
Choose:
-
Crisp poplin or fluid tencel
-
Belted waists or drop hems
-
Button-downs that can double as cover-ups
Pair with chunky sandals or platform espadrilles.
7. The Throw-On Blazer
Even in summer, British evenings can turn chilly. A lightweight blazer instantly elevates any outfit and transitions you from day to night.
Look for:
-
Linen, cotton or crepe blends
-
Slightly oversized or boyfriend fit
-
Colours like taupe, ivory, navy or blush
🌤 Blazers vary in cut—especially shoulder width and sleeve length. Use Tellar.co.uk to find your best fit before buying.
8. Flat Leather Sandals
Forget flimsy flip-flops. A structured leather sandal goes with everything—dresses, shorts, tailored looks.
Top styles:
-
Chunky two-strap sandals
-
Minimalist toe-posts
-
Velcro sport-sandal hybrids
Buy in tan, black or white to match your wardrobe. Look to brands like Dune, Ancient Greek Sandals, or Vagabond.
9. Summer Co-ords
Matching sets are going nowhere. A good co-ord set saves time and always looks cohesive. Opt for:
-
Linen shirt + shorts sets
-
Knit tanks + ribbed skirts
-
Crop top + wide-leg trousers
It’s the fastest way to look pulled together without effort.
And remember—top and bottom sizes might differ. Tellar.co.uk helps you get both parts right.
10. The Summer Bag
Switch your leather tote for something light, stylish and functional:
-
Raffia or straw bags
-
Canvas totes
-
Bucket crossbody bags
-
Micro bags in pastel leather
Choose one neutral and one statement option to rotate through.
Sizing Is Everything – Don’t Guess This Summer
You’ve found the perfect dress, blazer or co-ord—but the sizing is all over the place. A size 12 in Whistles might feel like a 10 in Zara or a 14 in Massimo Dutti. And international brands are even trickier.
That’s why Tellar.co.uk is your secret weapon.
