🧶 1. Jumper Styles & Who They Suit

1. Crew Neck Jumpers

Best For: Narrow shoulders, small busts, longer necks
Why: The high neckline draws attention upwards and balances a long torso
Style Tip: Wear layered over shirts or with statement jewellery to add dimension

2. V-Neck Jumpers

Best For: Fuller busts, wider shoulders, shorter necks
Why: Creates a vertical line that elongates the neckline and slims the chest
Style Tip: Ideal for hourglass and pear shapes when paired with high-waisted bottoms

3. Roll Neck / Turtlenecks

Best For: Small busts, long necks, rectangle shapes
Why: Adds volume around the neck and upper body
Style Tip: Choose ribbed for stretch or fine knit for layering under jackets

4. Funnel Neck / Mock Neck

Best For: Almost all body types
Why: A modern alternative to the turtleneck that offers warmth without bulk
Style Tip: Looks polished under tailored coats or styled with high-rise trousers

5. Boxy Cropped Jumpers

Best For: Petite frames, shorter torsos, rectangle and pear shapes
Why: Cropped lengths create waist definition and flatter proportion
Style Tip: Pair with high-waisted jeans or skirts

6. Longline & Tunic Jumpers

Best For: Apple shapes, plus-size, tall builds
Why: Skims over the tummy and hips while elongating the silhouette
Style Tip: Style with leggings or slim trousers to balance proportions

7. Cable Knit

Best For: Tall frames, athletic builds
Why: Adds visual weight and texture
Style Tip: Choose softer, thinner cables if you’re curvier to avoid bulk

8. Ribbed Jumpers

Best For: Slim or curvy builds alike
Why: Vertical lines elongate and streamline
Style Tip: Opt for ribbed roll necks for a chic, Parisian look

V-neck or mock neck under a blazer creates smart lines

For Casual Days

Go oversized or textured—think cable knits or brushed knits
Style with jeans, leggings or joggers for an easy weekend look

For Going Out

📏 6. Why Jumper Sizing Varies (and How to Fix It)

Sizing across jumper brands is not consistent:

COS Medium = H&M Large = Everlane Small (depending on fit)
Ribbed jumpers stretch differently than boxy cashmere or oversized knits
Necklines and sleeve cuts affect how size feels on different bodies

That’s where Tellar.co.uk steps in.
