Which was exactly why Mulberry felt like it had to move further upmarket, because it couldn't compete with MK etc at that price point. I do agree with the reasoning behind that strategy, and I think loyalists would have gone along with it if it had been implemented less aggressively. The market would still have grumbled at gradual price increases - that's happening everywhere - but wouldn't have necessarily abandoned the brand en masse.
Psychologically there's a big difference between having most of your visible offerings in the 3-digit price range and the 4-digit one. Top tier professional service firms are a great example of this: partner charge-out rates are just about £1k/hr but it's a source of great anxiety when to charge £1k as opposed to £975 per hour. In hindsight, Mulberry crossed that particular Rubicon without seemingly giving it much thought. No "the die is cast" type pronouncements from Guillon.
But I agree with previous commentors that the die
is cast on something like that. You can't raise RRP and then bring it back down without seeming like you cheapened the brand.
They might just have to do what Alexander McQueen does: eye-watering retail prices but almost everything is 50% off in the sales.
