That depends on your age and how much you want to spend, you don't know the shop selling more upmarket clothes than Barkers and you're there twice a week?
I've never bothered much with labels so I'm not sure about 'designer' clothing other than what I wore as a designer
Just googled it. It's a suit shop. I'm not going to know where it is as I have no need for a suit. But it's not really competing with Barker's smart / casual menswear business is it?
