Theory vs 3sixteen: which button-up wins?
Both land in the premium tier — the Theory Sylvain Structured Dress Shirt at $165, the 3sixteen 3sixteen Workshirt at $165. Here's how they stack up, head to head.
| Theory | 3sixteen | |
|---|---|---|
| Price | $165 | $165 |
| Material | Smooth stretch cotton, mid-weight, structured. | Indigo-dyed chambray, slubby Japanese cottons, and brushed flannel in mid-to-heavy weights that break in and fade over time. |
| Fit | Slim structured fit, true to size; trim through the body, best on lean builds. | Trim, slightly tapered work-shirt fit with a clean shoulder; built to layer over a tee without excess bulk. |
| Quality | Premium — smooth fabric, clean tailored construction, polished finish. | Strong stitching, sturdy buttons, and felled or reinforced seams reflect a workwear ethos. The heavier cottons are durable and improve with washing. |
| Best for | Modern-office tailoring, wearing under a blazer, and sharp slim silhouettes. | Raw-denim and heritage-workwear wardrobes, worn as a rugged layering shirt over tees and under jackets. |
| Care | Cold wash or dry clean per label; press for a crisp structured look. | Wash inside out in cold water to preserve indigo; expect some honest fading and a softer hand after the first few washes. |
Theory's $165 Sylvain is a slim, structured stretch-cotton dress shirt for sharp office tailoring, while 3sixteen's $165 workshirt is a trim heritage piece in indigo chambray and brushed flannel that fades and breaks in over time. Same price, opposite wardrobes.

Which should you buy?
Price is a wash at $165, so this is purely about what you wear. Theory is for the modern office: structured, slim, clean under a blazer, best on a lean build. 3sixteen is for raw-denim and workwear wardrobes where heavier cottons that age and fade are the appeal. Buy Theory for a sharp dress shirt; buy 3sixteen for a durable layering shirt with character.
