First and foremost it looks like corporate uniform, especially in the darker colours, other than that it just looks formal - pencil skirt, heels = office. Versatile, my backside!!!! Definitely not something to wear to a party unless you want to sweat your t*ts off, definitely not something you'd want to wear to meet friends for a coffee/mooch round the shops, you'd look over dressed and after the second shop, guess what? You'd be sweating your t*ts off! Wear it with Jeans, pleathers, or a "wellness trouser" (whatever that is) and you'd just look odd! "Sorry I'm late mate, but I couldn't find anything to wear on top, so I had to grab my work blouse"
Market the bloody thing as a work blouse, yep it might be sweaty, but it's easy care, but above all - reduce the price to what it's actually worth (about £12). Maybe, just maybe, the suggestion that we buy more than one wouldn't sound quite so ludicrous!
