Soap & Glory's Clean Girls - £6 for 500ml.
I got this body wash in the huuuge gift set Boot's like to cut to half price just before Christmas and I love it. I really do, I'm not really that much into buying expensive body wash but seeing as if was S&G I thought I'd give it a whirl. I've been using this since Christmas day so I apply it pretty much everyday (as does my mum!) and as you can see I have about a quarter left, to me it seems to have lasted a pretty long time! Plus one pump is a good handful for a leg so you get the picture on usage. Also this stuff smells divine. I love the fact that after my bath my skin still smells of the stuff and it's silky smooth.
At £6 for 500ml it does seem to be pretty pricey body wash but I'll definitely repurchase as I love the smell, it lasts a long time and me and my mum adore it!
