In Fenwick I tried on brassieres. One of them worth £145. That's more than I've paid for any item of clothing I've ever owned! Nice though. Very good fit. The shop assistant thought so also as she burst through the curtain unannounced and told me that there was good room in the back, cup size was perfect and my tan looked very fresh. I forget what it's like in these kinds of shops - extra helpful! A little bit over zealous!
And it all shut down well before late night shopping finished on Oxford Street. No need to work for people who can afford such items, perhaps.
