I've had a search set up on eBay for yonks now, looking for a particular dress I remember from the 80s - a flapper-style dress in t shirt cotton with broad black and white stripes with cap sleeves and a diagonal dropped waist. The stripes were vertical below the waist and diagonal - parallel with the slanted waistline - above.
There are GAZILLIONS of black and white striped dresses. I still haven't found this one - but the question occurred to me : -
How do dress designers avoid inadvertently violating copyright by accidentally coming up with the same or very similar design? Is there any sort of central reference they can check against?
