Harrods have updated their website to include proper pictures and sizes for items in all of their calendars. Looks like you get Rodial highlighter and blush drops which is nice.
I like Harrods but will probably skip it this year as I'm cool toned and I don't think that the lipstick and Apricot blush will suit me. I also have far too much skin care atm. Out of the ones released so far, I think that F&M is the one that I'm most likely to buy as it has more body stuff. Will wait and see what else comes out though (really, I don't need any!).
Looks like the fragrance calendar will be in store only on 1st Sept. Glad that I bought it in pre-order as I'm nowhere near a Harrods store!
