Fashion designer Trelise Cooper says she is shocked that a garment closely resembling one in her latest collection, is on sale in a British chain store, Top Shop.
A grey jersey with a red sequinned bow was featured in her catwalk show during New Zealand Fashion Week.
Ms Cooper says the design of the garment is her own, but her knitwear supplier in Hong Kong suggested the bow - and she liked it.
She says the supplier may have also sold it to the designer of the Top Shop jersey about the same time - and if that's the case, she will not be happy.
Ms Cooper has had intellectual property disputes in the past, challenging Arrowtown designer Tamsin Cooper over the use of the name Cooper.
