Louis Boston sees itself as a destination retailer (hence the salon, cafe, personal shoppers, etc.). So the people that shop there for the experience will undoubtedly continue to go. The walkins off the street will not. The question is, how much of Louis' sales are dependent on each of these two groups of customers?
I suspect alot of walk-ins go there for the curiosity factor and don't buy anything (I did that once - I was so appalled by the prices that I put my hand on my wallet and slowly backed out the door).
