Luxury swimwear label Zimmermann had better watch their back. After 22 years in the business Collette Dinnigan, one of Australia’s most internationally successful fashion designers is swapping lace for lycra with her swimwear debut. From what we can tell, the collection has a retro influence to it. Bustier-style bikini tops and bow-tie bikini briefs give way to a 1950s beach girl vibe. The collection is expected to drop sometime in August, so start counting the days until summer ladies.
