If your body shape is an apple (I prefer to call it a wide-waisted hourglass), you can buy skinny jeans to fit your waist (rather than your hips) and the end result is a very nice pair of straight jeans!
It is utterly possible that you can pay $30 for a lovely tween skirt suit from an op-shop and spend another $25 getting it dry-cleaned, only to find that the fabric is the fibre-equivalent of rabid fleas. If the itch weren't enough, you might still find a previously unnoticed tear on the back of the jacket, which is somewhere you'll normally never see a leather patch.
You can spend big bucks on a pair of low-heeled, well cushioned and super-supportive black shoes which a) go nicely with your black tights and skirts, and b) will be perfect for those 50-min walks home from work - and then realise they look EXACTLY like school shoes.
The big advantage of shopping where the customer service is terrible, is that you won't fee any obligation whatsoever to buy something from there.
