The Unstoppable Gray Flannel Suit

October 27th, 2016

The gray flannel suit has been part of the well-dressed man’s wardrobe for more than 100 years.

Stylish men of every era have been spotted in their own bespoke versions of this legendary cloth known for it’s elegance, masculinity, and versatility. In the 1920s it was Fred Astaire. It the 1940s it was President Truman. In the 1960s it was Sean Connery (aka James Bond). Arguably the best-dressed man of all time, Gianni Agnelli has spent a good part of his life in gray flannel. In the early 2000’s we saw it on Kanye West, and today it’s regularly spotted on menswear influencers like Nick Wooster and Alessandro Squarzi.

I think it’s safe to say that mid gray flannel is a staple menswear fabric that is built to last the test of time. The key is finding the perfect medium color, the ideal weight & texture and – as always – getting the fit right for your body type.

Here are a few of the hundreds of ways you can use a mid gray flannel suit to boost your entire Fall/Winter style.

    The Ultimate Fall/Winter Business Suit


    I wear a medium gray flannel suit (or at least the seperates) roughly once a week from October to March, because it’s incredibly warm, comfortable and versatile.

    I can wear it as a suit or separates with every one of my shirts, trousers and jackets, which is the key to curating a smart capsule wardrobe that allows you to “get dressed in the dark”. Think of it as making your life easier, and more stylish.



    The Ultimate Fall/Winter Jacket


    A perfect pairing for the mid gray flannel suit is our essential charcoal.

    You can mix-and-match each of the garments which, if you go with the 3-piece in both, gives you lots of smooth styling options.



    The Ultimate Fall/Winter Trouser


    Replace your jeans with gray flannel trousers, and you’ll quickly understand the added comfort and versatility.

    For plenty more styling ideas, remember you can always use the AoS Style Guide. Try searching by “Clothing Item” ->”Pants” -> “Trousers” -> “Gray”…for example.


    We’ve recently added a band collar as a design option for our custom shirts – which is the perfect update to the classic American oxford.


    The Ultimate Fall/Winter Leisure Suit


    As you probably know by now, I love wearing an unstructured suit without a shirt a tie – it’s often unexpected and always appreciated.

    A cashmere turtleneck and a tweed coat, for example, is an elegant and smooth way to stay warm and comfortable in cold temperatures.



    Thanks, as always, for reading.

    Yours in style,

      Hey Dan, You’re working with Southwick, and so maybe you can be the one to bring back the holy grail of trad / ivy menswear. I mean the single breasted, three roll two, cuffed and tapered pant Cambridge gray natural shoulder suit. I have one, Vintage 1960’s and I would sure love to get another to use without fear of ruining the original.

      The looks are money Dan. I always thought you should keep your look congruent and balanced by sticking with like fabrics. What I mean is pairing the flannel with a similar weight pocket square. You have a linen ps with wool flanne suit. Could you briefly go through your thoughts as to why you didn’t want to pair it with a heavier weight pocket square? Thanks!

      Dan, I don’t know how you manage to make an open DB jacket look so good. I always hate how they drape when open. Love the way the subtle pattern on that black jumper works so well with the flannel, too.

      Yea the Gray Flannel suit is pretty much a F/W staple.. I dont get to wear it for too long out here in Cali like I used to be able to when I was living on the east coast.. but I find I can wear out here when it gets cold without an overcoat.. it works just’s mine..Also its great to have you guys posting back regularly…congrats on the continued and growing success

        Is that a cufflink knot in your lapel?!

        • Esosa

          no, its a bunch of silk strands tied into two knots on either side.. it is a lapel pin..its small, innocuous and barely noticeable.. the perfect balance for the fit was my original idea..

          • JoeFromTexas

            “a bunch of silk strands tied into two knots on either side” – Isn’t that exactly what a silk knot cuff link is ( I thought you repurposed a cuff link into a lapel pin. Either way it’s a brilliant detail! (And one I may use myself)
