Halter tops were worn by retro cool girls, often as part of laidback ensembles. High-necked versions often featured backless designs, and crochet also played a key part for a hippyish feel. But there's something especially dramatic about a major plunge à la Farrah Fawcett that works perfectly for evening wear.Featuring a luxe-looking botanical print, Reiss' Luna top is reminiscent of a silk scarf. The piece is secured at the back and can be tightened in accordance with your preference. It features an open back, and would no doubt look killer alongside dark denim flares and vertiginous platforms.
