When investing in quality outerwear or urban fashion, knowing how a brand fits is just as important as how it looks. Add is one such brand that’s developed a loyal following for its stylish, minimalist approach to down jackets, coats, and cold-weather gear. But with European sizing and designer tailoring at play, the big question remains: Does Add run big or small?

In this guide, we take a closer look at Add’s sizing, compare customer experiences, and explain how Tellar.co.uk can help you instantly find your best size in Add and over 1,500+ other fashion brands.


About Add: A Technical Fashion Brand With Italian Roots

Founded in Italy in 1999, Add focuses on combining functionality with fashion — particularly in the realm of outerwear and high-performance coats. The brand is known for its:

  • Clean, refined silhouettes

  • Lightweight down materials

  • Unisex and gendered collections

  • Sustainability initiatives in production

Add appeals to consumers looking for sleek, urban outerwear that doesn't compromise on warmth or movement. However, its Italian heritage means the sizing can differ significantly from UK or US streetwear brands.


General Sizing Overview: Does Add Run Big or Small?

Women’s Add Sizing

Women’s styles from Add generally follow Italian/European sizing standards, which tend to run slightly smaller than UK sizing. Many UK customers report needing to size up by one size for a comfortable fit, especially in fitted styles or puffer jackets.

Note: Coats with an oversized or unisex cut may offer more generous fits. Always check product-specific sizing.

Men’s Add Sizing

Add’s men’s outerwear often includes slim tailoring, especially in lightweight jackets and minimalist designs. While it doesn’t drastically run small, taller or broader individuals may prefer to size up for layering room.

Many customers appreciate the high armhole and structured shoulder — a hallmark of Italian design — but this may feel snug if you’re used to relaxed-fit British styles.


Customer Reviews: Real Feedback on Add’s Fit

Across online retailers and fashion forums, customer reviews tend to align on a few common themes:

Pros

✅ Elegant cuts and flattering shape

✅ High-quality materials

✅ Lightweight but warm

Sizing Warnings

⚠ “Order a size up if you're layering over sweaters.”

⚠ “Italian sizing — beware if you have broad shoulders or a large chest.”

⚠ “Length was perfect, but sleeves ran tight.”

These fit comments are consistent with Add’s design ethos: streamlined silhouettes with tailored proportions. While elegant, they’re not always forgiving if you fall between sizes.


How Add Compares to Other Brands

When compared with other high-end outerwear labels, Add falls between Moncler’s slim fit and Canada Goose’s relaxed sizing.

If you're switching from UK or US brands to Add, don't assume your usual size will translate directly. Italian fashion typically prioritises structure and close fits, particularly in the chest and shoulder areas.


What Sizes Are Available in Add?

Add’s size range is broad, covering:

  • Women’s: IT 38–48 (UK 6–16)

  • Men’s: IT 46–56 (UK S–XXL)

However, availability depends on the retailer, collection, and season. Some online stockists list Add garments with both UK and EU sizing — but not always with body measurements included, which adds confusion.

Why Add Sizing Can Be Tricky Without Tools Like Tellar

  1. Italian Sizing Scales Differ – Add uses European sizes (e.g. IT 40), which are often mislabelled or approximated in UK stores.

  2. Unisex Styles Add Complexity – Some Add outerwear is designed for both men and women, with relaxed shoulders or neutral sizing.

  3. Layering Expectations – Add jackets often assume a light underlayer. If you wear jumpers underneath, you may need a different size.

  4. Retailer Inconsistency – Some stockists label Add with S/M/L, while others use numeric sizes or centimetres, leading to confusion.


How to Measure Yourself Correctly for Add

To use Tellar.co.uk or shop Add directly, here are the key body measurements you need:

  • Chest: Measure around the widest part of your bust/chest

  • Waist: Measure just above your belly button

  • Hips: Measure at the widest part of your hips

If you’re not sure, Tellar.co.uk offers a free measuring tape to anyone creating a profile — we’ll post it to you.


Final Verdict: Does Add Run Big or Small?

In summary:

  • Add tends to run slightly small, especially in fitted styles and Italian sizing

  • Size up for layering or if you’re between sizes

  • Always double-check measurements, especially for international orders

Whether you’re browsing Add for a premium winter coat or lightweight spring parka, the best way to ensure the perfect fit is to use a smart size-matching tool like Tellar.co.uk.
