Nice basic shirt
Fit Type: Regular Fit, Color: White Blue Mini Stripe, Size: Small
Very nice garment. Pretty much as it appears. I got the small and it is a good fit 5'4", 115lbs. The fabric is crisp cotton, medium/light weight, not shear, good body and hang, back shoulders have some fit. sleeves normal length. the collar needs to be re-ironed but, think it will be very good after that. Needs to have a pocket, but maybe I'll sew one on. The blue in the vertical stripe is medium denim shade, should go well with jeans. Sometimes I go for mediums, but think small is better with this particular shirt. Looks like a great everyday top.

Nice shirt, but noisy!
Fit Type: Regular Fit, Color: Navy, Size: X-Large
This is a nice crisp shirt, good styling and fit (maybe runs a bit large). I am returning it, though, because it is noisy! It reminds me of the sound of snow pants! I didn't know if that would go away after washing. Maybe if the sound doesn't bother you, it would be a solid choice.

Cute shirt
Fit Type: Regular Fit, Color: White Blue Mini Stripe, Size: Large
Well made and a great value. It has a generous cut which is good for my body shape and will work well worn without tucking it in.

Finally, a shirt that looks good on large chested women
Fit Type: Regular Fit, Color: White Blue Mini Stripe, Size: Large
I have a large chest and it’s really hard for me to find button up shirts that are fitted through the waist, but also can button up all the way without having that awful gap between buttons. The shirt fits like a glove is very comfortable very well made and had a great price too. I’ll probably buy more other colors.
