At Tellar.co.uk, we’ve analysed every single La DoubleJ product range and matched it to your actual body measurements. You’ll get a free measuring tape, one-time quick setup, access to your size in 1,500+ brands, and it’s always free to use—no catches. So you never need to check a size chart again!

🧵 What Makes La DoubleJ Sizing Unique?

Founded by J.J. Martin in Milan, La DoubleJ champions joyful excess. Think flared cuffs, tiered skirts, bold colour clashes, and free-flowing fabrics. But while the style is maximal, the sizing can be... inconsistent.

• Some garments are one-size-fits-most (OSFM)

• Others follow structured Italian sizing

• Fit depends heavily on fabric and silhouette

If you're shopping online from the UK, it's easy to misinterpret sizing—especially when products jump between generous fits and rigid tailoring.

📏 Does La DoubleJ Run Big or Small?

Short answer: Most La DoubleJ clothing runs generous or oversized—but some dresses, skirts, and fitted tops can feel small or structured in key areas like the bust or waist.

Let’s break it down further by category.

👗 La DoubleJ Women’s Sizing Breakdown

1. Swing Dresses, Kaftans & Tunics

• Signature pieces like the Swing Dress and Hendrix Kaftan are made for movement.

• These often run large and are meant to drape or billow.

• Many are OSFM or available in just two sizes (e.g., S/M and M/L).

2. Tailored Dresses & Blouses

• Items with darting, waistbands, or cuffs tend to run true to size or small.

• If you’re fuller in the bust, arms, or hips, sizing up is often advised.

3. Skirts

• Elastic waistbands are common, but tiered and A-line shapes can feel tight at the high waist.

• Check whether the fabric is structured or fluid.

4. Trousers

• Often cut wide-leg or flared, but waist sizing may follow Italian standards (tight and high).

• No stretch in fabrics like faille or silk—so size up if unsure.

5. Jackets & Outerwear

• Fit is variable: some coats are oversized and cocoon-shaped; others are sharply tailored.

• When in doubt, check shoulder width and sleeve length.

🛍️ What’s Worth Buying from La DoubleJ?

The brand blends fashion with function—great for travel wardrobes, special events, or everyday dopamine dressing.

1. The Swing Dress

A flagship item. Cut to flare from the bust with no waist definition, it suits many body types. Size down if you want a less voluminous look.

2. Kaftans & Shirts

Bold prints meet generous silhouettes. The best option if you want effortless elegance. Perfect for beach-to-dinner or layering over trousers.

3. Statement Skirts

Tiered, pleated, or printed, La DoubleJ skirts are wearable art. Be aware of high waistlines and rigid fabric.

4. Tailored Trousers

Cropped flares and silk wide-legs offer polished options—but double-check waist sizing.

5. Homewear and Accessories

Sizing not required—but the prints and luxury materials make these perfect gifts or entry-level pieces.
