The Smart Shirt Guide: Choosing the Best Shirt for Your Shape and Fit Goals

When was the last time you bought a shirt that fit perfectly—no gaping at the buttons, no tight shoulders, no excess fabric bunching at the back? For most, it’s rare. Shirts are among the hardest garments to get right, not because your body is the problem—but because the fashion industry lacks standardisation. One brand’s size 12 may fit like a 10 in another. Add bust shape, shoulder width, posture, and fabric behaviour to the mix, and the wrong choice becomes almost inevitable—unless you're using data.

That’s where tellar.co.uk comes in. As the UK’s leading free sizing tool, we match your real measurements to 1,500+ brands and styles—giving you exact shirt size recommendations based on your body shape and the technical specifications of each label. Below, we break down the best shirt types for every body shape, and offer brand-specific fit advice, technical shirt construction tips, and expert-backed links to help you shop smarter.

🧭 Why Most Shirts Don’t Fit Properly—and How to Fix It

Shirts demand structural precision:

• Bust-to-waist shaping affects gaping

• Armhole and sleeve pitch affect mobility

• Shoulder seam alignment controls the upper silhouette

• Fabric elasticity determines comfort and wearability

According to our tellar.co.uk, over 40% of women experience return-worthy fit issues with shirts due to poor bust accommodation and rigid, unforgiving fabrics.

👤 Know Your Body Shape Before Choosing Your Shirt

A shirt that flatters your figure must work with your body’s proportions—not against them.

Hourglass	Balanced hips and bust, defined waist
Pear	Narrow shoulders, wide hips
Apple	Fuller torso, narrow legs and hips
Rectangle	Equal bust/waist/hips, minimal curve
