Untucked shirts are a staple of modern casual and smart-casual wardrobes. They offer a laid-back yet polished vibe, perfect for weekend outings, relaxed work environments, or stylish streetwear looks. But getting the right fit is essential—too long and it looks sloppy, too tight and it ruins the comfort. This guide will walk you through how to size untucked shirts correctly to keep your look sharp and effortless.
1. Why Fit Matters for Untucked Shirts
Unlike dress shirts meant to be tucked in, untucked shirts are designed to fall at a specific length and fit your body in a relaxed but flattering way. A poor fit can throw off your entire outfit.
Benefits of a Proper Fit:
- Sharp silhouette without stiffness
- Comfort without looking oversized
- Balanced proportions for your frame
- No awkward bulging around the waist or hips
Getting the right size isn’t just about what number is on the tag—it’s about understanding your shape and how the shirt falls on your body.
2. Key Measurements to Consider
When sizing untucked shirts, focus on the following measurements:
Length
The shirt should fall mid-fly in the front and just below your butt in the back. If it covers your full backside or looks like a tunic, it’s too long.
Chest
You want enough room to move comfortably, but not so much that it looks boxy. Aim for a slim or regular fit depending on your build.
Shoulders
The seam should sit right at the edge of your shoulders. Too tight and the shirt pulls, too loose and it slouches.
Sleeves
For short-sleeve shirts, the hem should hit mid-bicep. For long-sleeves, the cuff should end at your wrist bone.
Waist and Hem
There should be a slight taper at the waist, giving your torso shape without clinging. Hemlines are usually curved or straight—straight hems are ideal for truly casual looks.
3. Body Type and Fit Tips
Different builds require slightly different approaches when finding the perfect untucked shirt.
Tall and Slim
- Choose shirts labeled “slim fit” with added length.
- Avoid oversized fits that drown your frame.
Shorter Build
- Look for shirts with a shorter overall length and a curved hem.
- Tailored or classic fits work better than boxy cuts.
Athletic Build
- Consider “athletic fit” styles that give more room in the chest and shoulders but taper at the waist.
- Avoid anything too loose—it can hide your natural shape.
Broad or Plus-Size
- Opt for regular or relaxed fits.
- Make sure the shirt drapes cleanly and doesn’t pull at the buttons.
4. Choosing the Right Brand and Sizing Chart
Not all sizing is created equal. Some brands cut their shirts shorter specifically for untucked wear, while others require tailoring or rolling the hem.
Pro Tips:
- Check if the brand offers “untucked fit” or “shorter length” options.
- Use the sizing chart—measure your chest, shoulders, and waist, and compare.
- Read customer reviews for sizing guidance and fit expectations.
5. How to Test the Fit
When trying on an untucked shirt, run through this checklist:
✅ Can you move your arms freely without pulling?
✅ Is the hemline sitting between the mid-fly and below the waistband?
✅ Does the shirt gently taper at the waist?
✅ Are the shoulders aligned and sleeves the right length?
If the answer is “yes” across the board—you’ve found your perfect fit.
6. Tailoring: A Game-Changer
If you’ve found a shirt you love but it’s just slightly off, don’t hesitate to have it tailored.
- Shorten the hem for a cleaner casual look.
- Add darts or tapering to bring in the sides.
- Adjust sleeve length for a more polished finish.
A small investment in tailoring can make a budget-friendly shirt look designer.
Conclusion
Finding the perfect fit for an untucked shirt is about more than just sizing up or down—it’s about balance, proportion, and tailoring to your body. Pay attention to length, shoulder placement, chest room, and hem style to achieve a casual yet refined look. Whether you’re dressing for the weekend or leveling up your everyday outfits, the right untucked shirt can be a versatile and stylish foundation for your wardrobe.
