High Drama, Bold Structure — But How Does The Attico Fit?

The Attico has quickly become one of the most coveted luxury labels on the global fashion scene. Founded by Gilda Ambrosio and Giorgia Tordini, the brand is known for its unapologetically glamorous silhouettes, sharp tailoring, and high-octane embellishments. But behind the aesthetic is a frequent sizing question:

What size am I in The Attico? And does it run small or large compared to UK sizing?

🧵 Want to find your size instantly? Create your free profile at Tellar.co.uk and see your fit in The Attico — plus your size in thousands of brands. One quick setup, always free. We’ve analysed every brand’s real-world sizing data, so you don’t have to guess.


Does The Attico Run Big or Small?

The Attico follows Italian sizing, and is known for structured, tailored, and close-fitting designs. Most pieces are cut slim through the bust, waist and hips — especially dresses, mini skirts, and suits.

If you're used to UK high street or American sizing, you’ll likely need to go up one full size in most Attico pieces.

Key Fit Insights:

  • Tailored items run small

  • Stretchy or draped styles are more forgiving

  • Dresses with zips or embellishment often need a size up

Sizing by Category

✦ Dresses

The Attico is famous for high-shine mini dresses, asymmetric hems, and hourglass tailoring. Expect tight fits — especially around the bust and waist. If a dress has sequins, corsetry, or zippers, it will likely run small.

🟣 If you’re curvy or between sizes, always size up.

✦ Blazers & Tailored Trousers

Sharp shoulders and cinched waists define most of The Attico’s suiting. While some oversized blazers are forgiving, most tailored styles are cut narrow through the shoulders and upper arms.

🟣 Trousers tend to have high rises and slim waists — size up if needed.

✦ Denim

The Attico’s denim collection offers both baggy jeans and ultra-high-waisted skinnies. Most styles are true to Italian sizing, which means snug at the waist and hips for most UK shoppers.

🟣 Rigid styles = size up. Stretch styles = true to size.

✦ Knitwear & Relaxed Shirts

The most forgiving category. Draped silk shirts, oversized knits and cropped cardigans are true to size, and work well on a range of body types.

What to Buy from The Attico

✔ Mini Dresses with Structured Shapes

Perfect for events — but they run small, particularly in non-stretch fabrics.

✔ Oversized Blazers

A signature look. Size depends on your style preference. Go true to size for the intended cut, or size down if you’re petite.

✔ Feather-Trimmed Pieces

Eye-catching and playful, but still structured. Check the bust and waist fit before selecting a size.

✔ Denim

Super stylish, but often snug. Rigid cotton = size up. Stretch denim = true to size.

Sizing Tips for The Attico Shoppers

  • Don’t rely on the visual silhouette — oversized designs may still be tight at key points (like shoulders or bust).

  • Always size up in rigid, woven, or embellished fabrics.

  • Curvier shoppers should be cautious with anything zip-fastened or structured — size up for ease.

  • If between sizes, size up across the board.

🎯 Tellar gives you real-time sizing tailored to your body and Attico’s cut
