Yes, you too, can smell like the Crawley family! Marks & Spencer is going to start selling soaps, candles, and beauty supplies when the next series airs in the fall. Not knowing the average price for these things in the UK, I can’t say whether spending £6 (or about $9) is a good deal.
If you’re in to this sort of thing, it would certaily help you complete the look with all the period clothes the producers have licensed out.
