Heidi Klein Core halterneck bikini top
From Farfetch
This black Heidi Klein Core halterneck ring bikini top has been crafted from a quick-drying stretch fabric and features a V-neck, ties at the back and neck and has a U-shaped gold tone metal ring detail to the front. Jack Black once said, 'No you're not hardcore. Unless you live hardcore.' We dropped out of the School of Rock early on and now identify with this Core bikini top instead.
