I think this dress is the perfect example of how bloggers can influence purchases a lot more than other media. I've never bought something online immediately after seeing it in a magazine, but when I saw Susie from Take-out in Couture in her cream/beige version of this dress, within five minutes I'd been on the Clothing at Tesco site and this white one was mine. If you like it, it's still on sale here, and the beige version is on half price sale here too. Just be aware you'll need to wear something underneith!
And if you like my turquoise necklace, feel free to go and buy on in my new jewellery shop :P They come in loads of other colours and gemstones too!
