Elegant and Comfortable.
Size: X-Large, Color: Light Beige
When I received this shirt, it looked wayyyy bigger than it actually is, due to the way it is cut.
The drawstring in the waist of the shirt is extended to the maximum when you get it, so it makes the shirt look extra wide.
But naturally, when you pull the top on and cinch the waist, the whole look comes together.
So make sure to order your actual size!
Don't be fooled by what you see when you open the packet!
There's some obvious texture from the horizontal weave in the linen, but the fabric is very soft.
The inner label says this shirt is 55% linen and 45% cotton and honestly? It shows.
It has a high amount of breathability without the shirt feeling flimsy. There's a slight amount of stretch, but it's not elastic. It doesn't feel cheap at all.
This would feel good to wear in an indoor and outdoor environment.
Paired with a camisole, I feel like you could dress this up or down.
The one drawback of it being natural fibers is that it has a tendency to wrinkle. But that's honestly fine for me.
I have an iron and I don't mind using it. lol
5 stars!

Impressive quality with a high end look and feel
Size: Large, Color: Light Beige
This Amazon Essentials linen blend shirt is beautiful. The quality is on par with high end brand tops that I have, and it does not disappoint. The light beige color is flattering and very versatile. The quality of the material and stitching is top notch. The fabric of the shirt is 55% linen and 45% cotton which is fantastic for the warmer months. The breathability and comfort are unsurpassed. The top washes well in a cold cycle, and I hang it to dry. I find that steaming the shirt after it dries takes out any wrinkles and really softens the fabric. The size chart is accurate for a relaxed look as described, but if you prefer a more fitted look you may want to size down. The drawstring waist gives the top a fun and flattering peplum look with a beautiful drape to it. Overall, I am thrilled with this shirt and would highly recommend. At the current price of $21.00 this is an excellent deal for a high quality top at an extremely affordable price. I just wish this came in more colors!

As advertsied but not for me
Size: Small, Color: Light Beige
The shirt is exactly as advertised. I did not find it flattering on me, and likely won't be wearing it. That doesn't mean it is a bad shirt, it just isn't the right one for me. If you want something lightweight for summer and like this shirt style, this may be a good choice. Otherwise, find something you like more.

Relaxed Fit Linen Blend Button Down Shirt
Size: Large, Color: Light Beige, Size: Large, Color: Light Beige
I like this shirt and it actually looks better than it does in the attached photo. The shirt is 55% linen and I took the photo without ironing because I wanted to show that this shirt is better than many linen shirts when it comes to wrinkles. In fact, I can steam the wrinkles out and don’t need to drag out the iron. The shirt is cool and comfortable. I like that you can use the draw string waist to make it more fitted. The button holes are a little small, which makes it harder for those of us who have arthritis to use. I will just leave most of the buttons fastened and slip the shirt over my head. It seems very well made. I looked it over carefully and did not find any loose threads or missed stitches. I think this is a good value.
