Focusing on old school tailoring without the stuffiness, as well as a sought-after ready-to-wear collection,  Joe and Charlie Casely-Hayford are the father and son duo behind one of London's most well-regarded menswear brands.

We caught up with them in their design studio to discuss their personal style rules.

We've just moved to North London. We have a strong Hasidic Jewish community, a strong Colombian community, a strong Polish community. All these things that make London so rich. It's rubbed off on us. I think that's why London is the fashion capital - it's this amazing abrasive, disparate clash of cultures.

On a very basic level people aren't in one place nowadays. Everyone has different identities they want to put out there. I think it's important as a fashion brand we allow men to do that.

I feel like luxury sportswear has really been absorbed into our culture now. It reflects the requirements of the 21st century guy.

Good shoes, always. You can wear crap trousers, but not shoes.

With a jacket or a pair of trousers, you can buy an inexpensive pair and get them tailored for not very much, and they will be transformed.

I've seen chinchilla coats coming back on the catwalk. I don't get it. 

I enjoy the freedoms of the punk era and the '90s. The anarchy, when there was less of a corporate style. It's more difficult to find these days.

My personal style derives from skinhead culture. So there isn't much variation in my wardrobe. I wear 12 hole military boots and cropped trousers every day. I think I own every colour of MA-1 bomber jacket, pretty much.

Having a simple wardrobe gives me more time to focus on other things. It's like if I worked in McDonald's, I'd probably never want to eat another cheeseburger again.

Reflect your own lifestyle. Don't slavishly follow trends.

I think to have a handful of investment pieces is a lot more exhilarating than a wardrobe full of fast fashion, which can be quite soulless. When you can put on a piece that lasts you 20-30 years, it's rewarding.

In an age when the market is so saturated, everyone's looking for that ounce of difference. I think that's why tailoring is trendy again.

People aren't conscious enough of their bodies. Everyone can look good, but it's about dressing for your body type. It's OK not to look like David Beckham.

I grew up in a generation where everything was available. Information has changed the game. Whereas with my Dad, there was this amazing feeling of standing at the precipice not knowing what's in front of you, so you just have to leap off.

I think that at the moment there's so much going on in the world politically, 30 years ago there would have been some kind of dress code or counter culture around that expressed people's views. I'm not seeing it. 

Supreme and Palace? They've created a gang mentality, it's always been there. A lot of high fashion brands are now creating their own gangs in order to survive. 

Sleep is for the weak! That's a family motto.
