Confused? escentual.co.uk have posted a blog post with further details and a guide to how you can tell which is which:
‘Miss Dior’ (with pink juice and packaging) – The new name for what was known as ‘Miss Dior Cherie’
‘Miss Dior’ (with yellow-ish liquid and packaging) – This will soon disappear from shelves, and be renamed ’Miss Dior Original’
‘Miss Dior Original’ – The new name for what was called ‘Miss Dior’ (The one from 1947)
Come back soon for news of Shalimar Parfum Initial being renamed Shalimar, No. 5 Eau Premiere being renamed No. 5 and A*Men Pure Malt becoming A*Men.....
Update: Elena from Perfume Shrine posted about this a few months ago : All That's Wrong with Perfume Nowadays - well worth a read.
Update 2: The Dior website shows both fragrances on a Miss Dior page. The original is now called Miss Dior Original. No mention of anything ever being Cherie.
