Great shirt. Fit perfect. High quality and not see through as some reviews suggested. I purchased 2 more once I received the first one. Highly impressedSharp and perfectly fitted, great value for a reasonable pricemy favorite shirtJust the cut expected.This is a very nice This is a very nice slim fitting button up shirt. I machine was on cold with tide original powder and gain scent boosters - I had no issues with color running ( color catcher in the washer) or drying on a tumble dry med heat. The shirt fit the same prior to washing as it did after - it just smelled a bit better! This is a casual shirt that is very comfortable and can be dressed up or down. This is slim fit and is comparable to J. Crew Slim fit shirts which is what I normally wear for my dress clothing at work. Although this is no where near as slim as my dress clothing - it is still slimmer then the regular fit shirts. The stitching is impeccable and the fabric is soft and a nice weave - so it should last for years with proper care.Size:17 inch neck34-35 inch sleeveActual Measurements:Neck- Runs closer to 16.5Pit to pit- 22.25 slightly tapers from pit downTop of collar to bottom front- 28 inchesTop of collar to bottom back- 32 inchesSleeve - 34 inchesImpressions:Having already owned DKNY shirts before, I knew this size ran closer to a large than an extra large. So, for me, I'm happy.However, I suspect if you're actually an Extra Large, 17 inch neck, and closer to a 35 inch sleeve, you won't.If you look at the actual measurements, this is sized like a 16.5 neck all day long. Slim fit should mean tapering, not half a size to a size small.In sum, if you're closer to a 16.5 neck in a traditional fit, this shirt fits great. However if you're closer to a 17 inch neck, it's going to fit tight.Cheers!===Disclaimer: I am not affiliated with the manufacturer and always write from my true experience.

Getting the right length so I can wear the shirt under a sport coat can be hard at times, since I like the sleeve to extend a bit from underneath the sport coat sleeves.DKNY does it perfectly in this long sleeve. It is more of a standard fit then a slim fit, which is fine, since it gives me some room to move, without ripping out a sleeve or shoulder like the Incredible Hulk...and I have done that in the past with a form fitting shirt.Nice shirt that fits well. That works for me.End of Review===Thank you for taking a minute out of your busy life to read my review.

I receive no monetary compensation for my reviews, but try to help potential buyers make an informed choice.I am a lady who enjoys wearing somewhat masculine clothing, so please consult other reviews for typical sizing questions. It actually feels a bit more feminine than I was expecting due to the slim fit, but still good at concealing a larger bustline (unlike many button down blouses in female sizing). Regardless of who wears it, this shirt is best worn with an undershirt (I recommend white).Men, do be careful... If this shirt disappears, check your partner's side of the closet ;)
