Choosing the Right Dress Shirt by Body Type
1. Identifying Your Body Type
Understanding your physique helps you select a shirt that flatters your frame and feels comfortable. Most men’s dress shirts cater to these general body types:
- Lean or Slim: Narrow shoulders and a trim waist.
- Average/Athletic: Proportional chest and waist, possibly a V-shape.
- Broad/Big & Tall: Larger chest, shoulders, or waist; above-average height.
Sizing Recommendations by Body Type
- Slim Build: Opt for slim or tailored fit styles; look for shirts with narrower sleeves and a tapered waist. Check alpha sizing (S or M) and pay close attention to chest and waist measurements in numerical sizing.
- Athletic Build: Consider athletic fit shirts or regular fit with a slight taper. These accommodate a V-shaped torso without excess fabric at the waist.
- Big & Tall: Look for extended sizes and big & tall ranges. Prioritize comfortable neck size, longer sleeves, and additional room in the chest and waist.
2. Choosing by Occasion: Casual, Formal & Beyond
Formal Occasions
- Look for: Numerical sizing for the most tailored fit (e.g., 16-34/35), classic or slim fit depending on body type.
- Color Palette: Crisp whites, light blues, pale pinks, or subtle patterns.
- Fabrics: High thread-count cotton, non-wrinkle or stretch poplin.
Business or Business Casual
- Look for: Both numerical and alpha sizing can work. Ensure appropriate sleeve length for showing some cuff under a blazer.
- Color Palette: Broad—solids, stripes, checks, or understated prints.
- Fabrics: Easy-care, wrinkle-resistant blends for daily wear.
Casual and Social Wear
- Look for: Shirts with alpha sizing (S–XXL), or casual “untucked” lengths.
- Colors & Patterns: Experiment with bold checks, patterns, denim, or chambray.
- Fit: Regular or relaxed fits for comfort and more movement.
Key Factors and Style Tips When Shopping for Men’s Dress Shirts
Understanding Shirt Sizing: Numerical vs. Alpha
- Numerical Sizing: Features precise neck and sleeve measurements, typically shown as “16-34/35” (neck-sleeve). Offers a more customized fit.
- Alpha Sizing: Relies on general size letters (S, M, L, etc.). Easier but less accurate; check brand-specific charts carefully.
TIP: Always prioritize numerical sizing for formal or tailored appearance. Alpha sizing is better for casual, relaxed shirts.
Getting Your Measurements Right
Accurate self-measurement is crucial:
- Neck: Measure around the base of your neck where a collar would sit. Insert one or two fingers for comfort.
- Sleeve: Start from the middle of your back neck, over the shoulder, and down to the wrist bone, with arm slightly bent.
- Chest: Measure around the widest part of the chest, keeping the tape flat.
- Waist: Measure around the natural waistline, usually just above your belly button.
Pro Tip: Use a soft (fabric) measuring tape for best results. If between sizes, size up for comfort—especially in more structured shirts.
Decoding Fit Types
| Fit Type | Cut Description | Best For | Style Effect |
|---|---|---|---|
| Slim Fit | Close to body, narrow sleeves and waist, higher armhole | Slim/athletic builds, modern look | Sharp, streamlined |
| Classic/Regular | Ample room in chest and waist, comfortable armhole | Most body types, timeless style | Polished, traditional |
| Athletic | Wider shoulders/chest, more tapered waist | V-shaped, muscular builds | Balanced, avoids bagginess |
| Relaxed | Extra room throughout | Broad waists, casual settings | Laid-back, easy to layer |
| Fitted | Between slim/classic, slightly tailored | Most men who want comfort with structure | Updated, versatile |
Selecting the Right Shirt Length and Sleeves
- Tucked or Untucked: Dress shirts designed for tucking are longer; casual or untucked styles are shorter, ending just below the seat.
- Sleeve Length: Standard variations are 32, 33, 34, 35, 36, and sometimes 37 inches. If you’re tall or have long arms, always check for “Tall” or “Long” fit versions.
Style and Accessorizing Tips
Coordinating with Suits and Ties
- For a business look, a classic (regular fit) or slim-fit shirt pairs well with a tailored suit and silk tie. Match your tie width to your collar type and lapel width for cohesion.
- Spread collars suit wide ties and formal settings; point collars are versatile and work for narrow ties or no tie.
- When wearing a tie, the tie knot should fit comfortably in the shirt collar without space or tightness.
Cuffs and Collars
- Cuffs: Barrel (button) cuffs are standard. French (double) cuffs are formal and require cufflinks.
- Collars: Spread, point, and button-down are the most common. Spread collars look sharp with wider tie knots, while button-downs are perfect for business casual.
Color, Fabric, and Pattern Choices
- Stick to light colors and solids for versatility in formal settings.
- Explore stripes, checks, and patterns for business casual and daily wear.
- For high activity or travel, choose wrinkle-resistant, performance, or stretch fabrics.
Practical Tips & Best Practices for Buying and Wearing Dress Shirts
- Try Before You Buy: Whenever possible, try shirts on with your intended trousers and jacket to ensure shoulder, collar, and sleeve fit.
- Check Brand Charts: Use each brand’s specific sizing chart—there can be variations of up to a full size between brands.
- Wash and Care: 100% cotton shirts may shrink slightly after the first wash. Consider this and follow laundering instructions for fabric longevity.
- Alterations: If your measurements fall between sizes, prioritize fit at the shoulders and chest, then consider tailoring the waist for a perfect fit.
- Wardrobe Essentials: Every man should own at least two classic white dress shirts, as well as versatile blue, patterned, and occasional bold colors for variety.

FAQ
What do the numbers on men’s dress shirts mean?
The first number is the neck circumference in inches (e.g., 16 means a 16-inch neck); the second is the sleeve length, also in inches (e.g., 34/35). This system helps ensure a more tailored fit.
How do I measure my neck for a dress shirt?
Wrap a soft measuring tape around the base of your neck, where the collar rests. Leave enough space for one finger between your neck and the tape for comfort. Round up to the nearest half-inch.
What’s the best way to check sleeve length?
With your arm slightly bent, measure from the center back of your neck, over the shoulder, and down to your wrist bone. Round up to the next available sleeve size.
What fit should I choose: slim, regular, or athletic?
Choose slim if you’re narrow or prefer a modern look; regular/classic for most body types and traditional settings; athletic if you have broad shoulders and a narrow waist.
Are alpha (S, M, L) or numerical sizes better?
Numerical sizes are more precise and recommended for tailored or formal shirts; alpha sizes (S, M, L, etc.) are easier but less accurate, best for casual shirts or when the fit is forgiving.
Do dress shirt sizes vary between brands?
Yes, sizing can differ by manufacturer. Always check each brand’s size chart and, if possible, try the shirt on or order multiple sizes if shopping online.
How can I ensure my dress shirt fits well?
The shoulder seam should sit at your shoulder’s edge; the collar should be snug but not tight, and the sleeves should end just past your wrist. The shirt should fit without pulling or excessive billowing.
What if my measurements fall between sizes?
Size up for comfort, especially around the neck and sleeves. For a slimmer silhouette, shirts can be tailored at the waist or torso after purchase.
Which shirt length is best for tucking in?
Dress shirts designed for tucking are longer, reaching below your hips or seat. “Untucked” or casual shirts are shorter and should end just below the belt or seat.
Can dress shirts be altered for a better fit?
Yes, most quality dress shirts can be tailored for adjustments at the waist, sleeves, or even the collar. Shoulder width is less adjustable and should be correct from the start.
