Is Jaeger True to Size?

Mostly Yes—But It Depends on the Item

Jaeger tends to run true to size for structured garments, but relaxed pieces or knitwear can run slightly large. Their modern collections blend sharp tailoring with relaxed layering, so your experience will vary depending on what you’re buying.

📌 Tellar’s live data shows:

• Structured jackets and trousers tend to run true to UK high street sizing

• Tops, knits, and relaxed dresses can feel roomier—ideal for a more casual fit

• Their sizing is consistent, especially since being acquired by M&S, but still differs slightly from brands like Dorothy Perkins or FatFace

How Does Jaeger Compare to Other UK Brands?

If you’re shopping across multiple brands, here’s how Jaeger fits in:

• More tailored than M&S, but more generous than Zara

• Similar to Hobbs for suiting, but with more relaxed weekendwear

• Less snug than Whistles, especially in knitwear

• More premium in cut and fabric than Next or Oasis

This makes Jaeger ideal if you prefer polished, slightly generous fits without going oversized.

Best Items to Buy from Jaeger

Jaeger is known for investment pieces—clothing that lasts both in quality and style. These are our top recommendations:

1. Wool Coats and Trench Coats

Crafted from premium wool blends, Jaeger coats are a standout. The tailoring is clean, with room for layering. True to size for most, but Tellar.co.uk can help if you’re between sizes or broad-shouldered.

2. Structured Blazers

These are the brand’s most iconic pieces. Whether single-breasted or double-breasted, the fit is elegant and modern. Great over blouses or rollnecks.

3. Relaxed Knitwear

Jaeger’s jumpers and cardigans are ideal for layering or off-duty wear. Sizing is generous—often best to size down for a neat fit, or stay true to size for comfort.

4. Silk and Cotton Shirts

From pleated bib fronts to collarless styles, these shirts offer high-end detailing. Fit is true to size across most body shapes.

Sizing Pitfalls to Watch Out For

Though Jaeger is largely consistent, we’ve seen a few common user-reported issues:

• Waist gaping in tailored trousers for curvier figures

• Bust tightness in blouses with no stretch

• Longer sleeve length on blazers for petite frames

These are subtle, but impactful. Tellar.co.uk cross-references your measurements with Jaeger’s database, helping avoid these pain points instantly.
