Is an inbetweenie ready for pret-a-porter clothes???

After reading this article on The Curvy Fashionista: do we want nice things? This is very interesting. When I am going to net-a-porter and search clothes in my size XXL, there’s a very small selection. And nothing I wanna have. There’s nothing of my favorite designer: only casual pieces of Vivienne Westwood and some items of Marc Jacobs I DO NOT want to have. And YES: I want nice things. Most of the time I buy cheap stuff, the only reason because the cheaper shops go up to size 46!
So the solution will be: make my outfits look like designer…
What do you think about designer clothes or nice looking items? Is an inbetweenie ready
for pret-a-porter clothes???
