Hi all!
I have just bought my first pair of Spanx Shapewear
http://www.slimmingsolutions.co.uk/acatalog/Spanx-Shapewear.html and I couldn't believe how fantastic they are!! I purchased them for a work function as I wanted to look much slimmer than I am infront of the big bosses

There are quite a few types to choose from and I was deliberating for several hours but decided on the higher power panties. I was suprised at the no visible panty lines you get with a lot of other slimming underwear, but these were certainly well worth the money. I am considering purchasing them in black, however I don't know which clothing those would go underneath - I do wear alot of light colours. Maybe the thong panties in nude may work good for me too.
