Casual dress shirt
Size: Medium, Color: Powder Blue Vertical Stripe
I purchased a shirt for my fiancé for vacation wearing to church and just upscale casual wear around town and he loves it. He washed it and dried it and it looks good as new. He also thinks that it runs true to size and is comfortable to wear. The only note is that the fabric is a bit more thick than the other dress shirts that Amazon offers so it’s not optimal if the weather is very hot, otherwise the look is great

Very nice
Size: Medium, Color: Pale Pink
Fits great, looks great and feels great. The material is much softer and structured than it appears.

Pretty good.
Size: XX-Large, Color: Pale Pink
I've bought this before, the shirt is kind of stretchy and kind of thick. It's nice quality when you get it at some discount. Beware that this is slim fit so get one size up if you want to be comfortable.

PERFECT FOR THE SUMMER
Size: XX-Large, Color: Pale Pink
Pleasantly surprised with this shirt. More pink than in the pic. The material is a bit thicker than expected (like a thin canvas) but breathable and perfect for the summer. Perfect fit for my 240ish build (2XL). Highly recommended.
