These $100 casual dress shirts from Charles Tyrwhitt are a departure from its pricier classics - we tried them to see if they're worth it

I looked at the price tag and thought, who would pay over $100 for a cotton/linen blend? I, for one, want 100% fine Irish or French linen at that price. And even after feeling how soft (cotton) yet flowing (linen) this twill shirt is, I don't disagree with myself in retrospect. It's a bit on the steep side, at least for my taste in fashion.

But I can't deny that the 77% Cotton/23% Linen Twill Shirt I'm testing out is made well. It's finely stitched (as in, I can hardly find the stitching); the fabric, again, is soft as can be; and after repeated use (including a dip or two in the Atlantic) and several trips through my cheap and merciless washing machine, it's holding up.

What gives these shirts their buying point, in my opinion, is that if you buy multiple shirts, you can get them for about $50 apiece. At that price, this shirt is an absolute steal. –Owen Burke, Insider Picks senior reporter

I first came across Charles Trywhitt about two and a half years ago when I needed to refresh my selection of dress shirts. While performance dress shirts have become a huge part of modern workwear and my closet specifically, Charles Tyrwhitt remains my favorite brand for good-fitting classic shirts (I'm actually wearing a Charles Trywhitt shirt in my author page photo).

Being a big fan of the brand already, I was excited to try the new casual designs, and they were exactly what I was used to, just less formal. I have a very slim build, so the extra-slim shirt fits to my body well, which is an important part of properly executing a button-up. The brand offers a full range of fits, so men of all different body types can still get a shirt that fits them well.

If you think $110 is a lot of money for a button-up shirt, I completely agree with you. However, the key to getting around the price is to bundle them. You can get four shirts for $199 (or $49.75 each) — and at that price, I'm all in. –Amir Ismael, Insider Picks commerce reporter

I am not opposed to spending $100 or more for a high-quality shirt, but I expect it to fit great, feel comfortable, and hopefully, hold up for years, which is what I am noticing with the extra slim fit soft washed stretch poplin shirt (in navy) from Charles Tyrwhitt's casual collection.

After weeks of testing, I found the shirt to have a nice fit, considering it's ready-to-wear. With shirts like this, I normally would need some alterations, but that wasn't necessary here. The shirt can be worn tucked-in or loose, and it looks great either way and is appropriate under a suit or relaxed with jeans. I'm a bit stocky, but the extra-slim cut gives the illusion of a slimmer build. The stretchy poplin weave makes it comfortable to move around, and I like that it's 100% natural cotton and not some synthetic fabric.

Charles Tyrwhitt says this shirt's poplin weave is its lightest and most breathable, but I found that it is still a bit weighty. I also wore it during the height of summer, and while I didn't feel any major discomfort, I did wish it was a bit more breathable. My recommendation is to wear this shirt year-round except during hot and humid summer days (switch to linen or cotton/linen blend for those scorchers, like the Slim fit bright blue cotton linen twill short sleeve shirt that my colleague Owen Burke tested).

I machine-washed and line-dried the shirt twice. I also threw it into the last 10 minutes of a dryer cycle on low heat. So far, the shirt has held up nicely, and I haven't noticed any weird creases or folds, and I expect it to maintain its quality down the line. Do hang it and use a light iron or steamer because it can get super-wrinkled otherwise. –Les Shu, Insider Picks guides editor
