    Look Good Feel Good!!!
    Size: XX-Large Big Tall, Color: Lilac
    The shirt is verey stylish the price point is good quality is good. Ordered a size down the first time because i tried using size chart. My opinion if you normally wear a certain size in another brand you like, consider ordering that size. I say this because I ordered down one size from my normal King Size brand and had to return. New one fits perfect recieved lots of compliments on the color. So I recommend this brand and this shirt for those of us who may be on the BIG size and enjoy a little room in their fit

    Color and size were great, but it came with some wrinkles and creases.
    Size: 5X-Large Big Tall, Color: Olive Green
    The color (olive green) and size were perfect. The shirt is comfortable, and i did not see any bad stiching. The fabric is a synthetic and it came with a bunch of wrinkles and creases. I'm hoping with several wears and washings that the initial wrinkles will smooth out -- if that happens, then I'll update this review.

    Sizes differ
    Size: 3X-Large Big Tall, Color: Pink
    Sizes differ from each style shirt. A 3X in one style does not fit the same as a 3X from a different style even though it is the same company. The ones that I could find that fit were a nice shirt and comfortable. I would not rule out COOFANDY after trying one style shirt. To be honest I can’t remember if I kept this shirt or returned it but the return policy allows you to try different shirts so well worth the money to give it a shot. I needed a pink shirt to match my wife’s dress so I tried a couple different ones and ended up with a couple nice shirts at a reasonable price.
