Sixth form suit for a skinny boy. 🙏

[WillTraynor]

Apologies this isn't S&B but I'm trespassing on your good nature for traffic.

Does anyone know where I can get a boy's sixth form washable suit with a 28" waist? Preferably charcoal. I'm trying to avoid the wedding-type suits as they tend to be neither charcoal nor washable.
I assumed I'd get one easily at M&S or Next, but apparently my boy is skinnier than I realised. ☹️

You may not want to hear this, but we ended up at Charles Tyrwhitt for our son's. He was also a 28 inch waist and 6'4", so could not find a thing anywhere!

The suit was expensive but great (we ended up buying 2 so we could rotate them with dry cleaning...sigh). Sadly I donated it to a charity shop years ago or you could have had his!

We got one (washable!) at M&S 4 years ago. Would also try Slaters menswear if you are anywhere near Manchester - DS is also long and skinny and got a great one there ... but it wasn't washable.

Are these not washable? I’m not sure I’ve ever seen a washable suit jacket, but the trousers should be.

Slim fit Next was my first hunch and they do this one
