The duo launched with the Original knicker, a “wedgie-free” bikini brief that sits low on the hip and offers “ample back coverage” (£18, stripeandstare.com). Nearly a decade on it still accounts for 43 per cent of total sales. Formerly crafted from cotton, it is now made mostly of Tencel, a cellulose fibre derived from wood pulp, which is breathable, moisture wicking and antibacterial (there is a 5 per cent elastane to ensure the knickers don’t fall down). The brand is also experimenting with innovative materials such as Lenzing, Ecovero, Viscose, Seersucker and Eco Mesh made from recycled plastic bottles. I am a particular fan of its Hipster knickers, which are high-waisted — more of a boyshort — with a lace trim, available in nude and colourful multipacks (£50, stripeandstare.com). First-time buyers can also try a Discovery Pack which includes four styles (Original, High Rise, Brazilian and Thong) to put to the test (£50, stripeandstare.com).
