Disposable shirt
Size: 15.5" Neck 34"-35" Sleeve, Color: Black
This is a disposable shirt - which is largely to be expected at this price point. It's mostly polyester, super thin and slapped together. The fit is not terrible if you have broad shoulders and long arms if you buy the correct size (I frequently run into shirts that are several inches shorter in the sleeves than advertised). If you need a shirt for your job or an event and don't expect it to last too long you'll likely be happy with getting a handful of wears out of it before it inevitably falls apart.

Spot on!
Size: 16.5" Neck 32"-33" Sleeve, Color: Lemon Glaze
Fits really well. Not for fatties. Pale yellow is nice. Collar stays are sewn in and permanent.

Love these shirts
Size: 18.5" Neck 36"-37" Sleeve, Color: Persian Blue
Beautiful dark blue color. Soft and well made. Comes out of dryer with minimal wrinkles but not starched looking. A little bit of stretch to it. Does not have the neck extender button. It is a slimmer cut through the waistline for those with wider shoulder but not a bigger belly. It is lightweight especially for FL summers but not thin and see through. Great shirt for work.

Awesome.
Color: Silver Blue Brown
Loved it! I can hardly hear it run, its so quiet! It's very easy to read and looks quite classy. The leather strap has also held up very well to normal wear.
