Let me start by saying this shirt surprised me. The 95% cotton blend feels like a second skin - soft but with enough structure to look polished. I wore it to a casual Friday at work with dark jeans and got three compliments before lunch.
The mandarin collar is what sold me initially, but be warned: it runs large. At 5'10" and 160lbs, my medium fits perfectly everywhere except the neckline which gaps slightly. Not a dealbreaker, but I wouldn't wear it without an undershirt.
Washing has been interesting. After three cycles (cold wash, line dry), the color hasn't faded but it did shrink about half a size. That actually improved the fit for my slim frame. The spandex keeps its shape remarkably well - no saggy elbows yet.
Pro tip: Size up if you're between sizes or have broader shoulders. My gym buddy ordered his usual large and now uses it as motivation not to skip arm day - the sleeves get tight fast.
Is it perfect? No. But for under $30, this polo bridges that gap between 'too casual for work' and 'too stuffy for weekends' better than anything in my closet right now.
