Named after the Aventine Keyhole in Rome, the Aventine Tank is a wide shoulder, sleeveless top with a diagonal keyhole detail. The pattern has two closure options: i-cord ties or a clasp/brooch closure. The Aventine Tank is knit in Undine DK from Ritual Dyes - it is the perfect summer cotton/linen blend and is even machine washable!
