The Knot Bottom

{{ price }}



Make a major impact in the new Knot Bottom swim brief. A riff on an original Rudi Gernreich 1970s style, cut-out sides deliver an immediate ‘XXX’ punch. Knotted double straps create a ‘suspension bridge’ over your haunch, neatly linking front and back panels together - and exposing the sexiest slit of the hip-top. An exercise in engineering as well as style, the package is lifted, defined and balanced by the full-brief back. In addition to bold Black and stand-out Ivory colourways comes sizzling new Pop-bright Hot Pink. You’ll be proud to show up - and show off - in all three.  Free US Shipping on all orders.
