Boohoo is one of the UK’s most recognisable fast-fashion names — delivering trend-led, affordable styles in everything from night-out dresses to everyday loungewear. But its fast turnaround and wide product catalogue raise an important question for online shoppers:
Does Boohoo run big or small — and how do you know what size to order?
In this complete guide, we’ll break down how Boohoo fits, how it compares to premium brands like Borgo De Nor, and how Tellar.co.uk gives you your perfect size — instantly, accurately, and for free.
What is Boohoo’s Typical Sizing Like?
Boohoo uses UK sizing by default, and its garments are produced with mass-market sizing in mind — but actual fit can vary wildly depending on:
-
Garment cut
-
Fabric (stretchy or rigid)
-
Intended silhouette (fitted vs oversized)
In general:
Boohoo runs true to size to slightly small, especially in fitted dresses, trousers, and tailored tops.
| Category | Sizing Fit |
|---|---|
| Bodycon dresses | Small – often tight in waist and bust |
| Oversized tops | True to size or generous |
| Jeans & trousers | Small at waist and hips – size up if curvy |
| Coats & outerwear | True to size |
| Co-ords & loungewear | Slightly small, but flexible due to fabric |
| Occasionwear | Tight-fitting, especially in bust or sleeves |
If you’re between sizes, size up — especially for dresses and trousers.
What Shoppers Say About Boohoo Sizing
Feedback collected by Tellar.co.uk confirms recurring sizing concerns from real UK shoppers:
-
“Boohoo sizing is hit or miss — some dresses are fine, others are like two sizes too small.”
-
“Trousers came up short and tight even though I ordered my usual size.”
-
“Had to size up in the bust or it wouldn’t zip.”
-
“The oversized hoodie was massive. Definitely depends on the fabric and cut.”
This variation makes size charts unreliable — which is exactly where Tellar.co.uk steps in.
How Boohoo Compares to Borgo De Nor
On the other end of the market, Borgo De Nor — a luxury London-based designer label — offers structured, feminine dresses known for bold prints and flattering tailoring. But while their branding differs wildly from Boohoo, shoppers still face a sizing dilemma.
| Brand | Fit Profile |
|---|---|
| Boohoo | Trend-led, bodycon-focused, often cut tight in bust/hip |
| Borgo De Nor | Designer fit, slim in waist, true to size at bust, some dresses run short in torso |
Tellar.co.uk shows that Borgo De Nor tends to run small in the waist, especially in rigid cotton and crepe fabrics, while Boohoo runs small in more areas (waist, bust, and length — especially in occasionwear).
Both brands can confuse shoppers without brand-specific guidance — which is where Tellar’s live fit database helps bridge the gap.
Why Size Charts Aren’t Enough
Most brands show basic bust-waist-hip measurements in a static chart — but here’s why that fails:
-
They don’t adjust for fit type (e.g. tailored vs oversized)
-
They don’t reflect your body shape (e.g. curvy waist-hip ratio, longer torso)
-
They ignore fabric behaviour (e.g. jersey vs poplin)
-
They assume consistency across collections — but Boohoo varies dramatically
That’s why Tellar.co.uk was built — to deliver accurate, real-time size recommendations, not vague averages.

When to Size Up in Boohoo
Based on Tellar’s sizing data and thousands of user reviews, we recommend sizing up in Boohoo for:
-
Bodycon or occasion dresses – often very tight in bust and waist
-
Trousers & co-ords – snug in the hip/waist, especially with zip or no stretch
-
Playsuits – short in torso
-
Fitted blazers – narrow in sleeve and upper back
For oversized tops, slouchy jumpers, and elasticated loungewear, true to size usually works fine.

Final Verdict: Boohoo = Trendy, Tight-Fitting, and Inconsistent
If you love Boohoo’s fun and affordable styles but hate sizing surprises, you’re not alone. With variation across fabric types, fits, and cuts — even within a single collection — it’s risky to rely on a static size chart.
And for premium labels like Borgo De Nor, the same issue applies — just with more expensive consequences when the size is wrong.
That’s why Tellar.co.uk is your wardrobe’s secret weapon.
