Overview: In The Style Sizing – A Mixed Bag
Known for Fast Fashion, Not Size Consistency
Like many fast fashion brands, In The Style offers budget-conscious garments produced at speed. This means that fabric variation, supplier inconsistency, and rapid production can result in unpredictable sizing.
Common customer feedback suggests:
-
Waistbands often come up tight
-
Bust areas are sometimes generously cut
-
Trouser and sleeve lengths can be inconsistent
-
Size tags don’t always reflect real fit
Fit Verdict: Inconsistent. Dresses and trousers run small. Tops and casualwear are often true to size.

Is In The Style True to Size?
Dresses: Often Run Small
In The Style is known for its bodycon dresses and influencer-led glam drops. These styles often use non-stretch polyester blends and are cut for a tight silhouette, which means the fit is frequently on the small side, particularly around the waist and hips.
Example: A UK 10 customer may find a size 10 In The Style dress fits more like a UK 8.
Fit Verdict: Runs small in figure-hugging styles—size up for comfort.

Co-ords & Casual Sets: Generally True to Size
From loungewear to jogger sets, these items tend to be roomier, often made with elastic waistbands or soft jersey. This makes them more forgiving and closer to standard UK sizing.
Fit Verdict: True to size or relaxed fit—safe to order your usual UK size.

Tops & Blouses: Slightly Generous Cut
Tops with balloon sleeves, cropped fits, and smock styles from In The Style tend to allow a bit more room, which can be helpful for those with broader shoulders or a fuller bust.
Fit Verdict: Runs true to size or slightly large—no need to size up unless fitted.
Jeans & Trousers: Inconsistent and Often Tight
This is where most fit complaints lie. Jeans and trousers often come up tight in the waist and hips, especially if made from rigid denim or non-stretch polyester. Many customers suggest sizing up, especially in high-waisted styles.
Fit Verdict: Runs small—size up if between sizes.

In The Style vs Standard UK Sizing: Chart Comparison
| Size Label | Bust (cm) | Waist (cm) | Hips (cm) | UK Equivalent |
|---|---|---|---|---|
| 6 | 80 | 62 | 86 | UK 6 (accurate) |
| 8 | 84 | 66 | 90 | UK 6–8 (runs small) |
| 10 | 88 | 70 | 94 | UK 8–10 |
| 12 | 92 | 74 | 98 | UK 10–12 |
| 14 | 96 | 78 | 102 | UK 12–14 |
Takeaway: In The Style’s sizing chart appears standard on paper, but actual fit—especially in tighter styles—often runs up to one size small.
Fabric Type & Sizing Accuracy
Material matters more than you think. With In The Style, sizing variation often correlates with fabric choices:
-
Rigid polyester → tight fit, no stretch
-
Viscose or crepe → slightly forgiving but can cling
-
Jersey/stretch knits → generally true to size
-
Elasticated styles → relaxed fit
Pro Tip: Always check the stretch factor. Non-stretch = size up. Stretch = regular size or down if in doubt.
