About Jigsaw: A British Classic

Founded in London in 1970, Jigsaw is a heritage British label offering elevated wardrobe essentials. From wool-blend overcoats to silk midi dresses, the brand balances comfort and polish, making it a go-to for professional wardrobes, special occasions and understated everyday wear.

With its own UK sizing system and commitment to natural fibres, Jigsaw is often viewed as more generous than fast fashion counterparts—but that doesn’t mean sizing is always straightforward.

So, Does Jigsaw Run Big or Small?

Overall Verdict:

Jigsaw generally runs true to size, leaning slightly generous—especially when compared to brands like Reiss or Zara. However, fit varies by garment type, and certain styles (like tailored blazers or slim-cut trousers) can feel snug depending on your proportions.

Key Fit Summary:

Jigsaw Size	Fit Notes	UK Equivalent
6	Runs true to UK 6	Slim fit
8	Roomy at hips, true to size	UK 8
10	Slightly relaxed through waist	UK 10
12–14	Generally comfortable	UK 12–14
16+	True but varies by fabric	Check stretch

Don’t rely on labels alone—Tellar.co.uk’s Size Lookup Tool gives you personalised, data-driven size recommendations using your real body measurements.
