Very complicated question...
without hearing about the LV store closing, i would have told you the situation of the luxury markets in general was fine. Even with the crisis and all that, I have read Bernard Arnault and Yves Carcelle say they are still going to keep growing in double digits (as they've been doing in recent years). They have stated that even if the european and north american market could suffer the consequences of a finantial crisis, the significant growth of other markets like russia, china, japan, dubai, and other countries that concentrate more and more money everyday in a few hands was gonna keep them out of trouble.
However, closing a store is no good sign... it's of course no terrible news, as they have tens (if not hundreds

) of stores in the country , but it's something to keep an eye on.
Do we know why the store was closed? maybe they are just opening another one in a better area/building. there could be other reasons to shut it down, non negative-profit related
it really seems surprising... no other label has closed yet?
