This might be a really stupid question but I am rapidly outgrowing all my clothes, and not really ready to admit - even at 15 weeks - that I'm pregnant (not sure I ever will be, to be honest, that's just the way I roll). I went into Mothercare to price things up generally and saw their maternity section which I had a mooch round - whilst sweating the coldest sweat... It really wasn't "me" and it was all dead pricy for stuff I might only wear for a couple of months.
Why can't I just buy a size up from my normal size? And then do some hardcore washing to try and shrink it down to my normal size afterwards perhaps 
Or am I being really naive?
