The 38-year-old former Spice Girl looked delighted not only to make her own fashion debut – but to show off her toned and tanned curves too.
Talking about the collection, Geri told MailOnline: ‘It’s about inspiring confidence with great looking swimwear for all body shapes.’
She has said previously: ‘It’s for real women of all shapes and sizes. Everything is mix and match, so you can choose the exact shapes and styles that suit you.
‘This is a collection that makes you look good and feel fabulous.’
The pieces, from the ‘Geri by Next’ collection, will be on sale at the high street retailers or via next.co.uk from next month
