Collins is expected to work with current managing director Vanessa Gold and chief executive Jacqueline Gold, while it is uncertain which department Amosu will work in. The pair previously worked at Asos and Arcadia, with Amosu gaining experience at New Look and Next, before joining Game for two years.
The lingerie retailer has also added to its non-executive board by appointing Mark Gifford, a former chief financial officer at House of Fraser.
CEO Gold, said: “In 2018 we made a substantial investment in a brand relaunch, as well as our technology and IT systems, which is enabling us to digitally enhance our customer experience. At this progressive time for Ann Summers we felt the time was right to bring in more talent as we look to the future of the business.”
