I've worn this a few times as Pilates wear, but it's been sitting in my closet since then. Size: 6 According to Lululemon's official website, size 6 is for a bust of 86.5 cm. Please understand that this is a used item, so I would appreciate it if only those who understand this would consider purchasing it. The item will be folded and packed for shipping, so please be aware that there may be some wrinkles.
