g this week, curating a mini exhibition to coincide with a retrospective of his work at the Whitney Museum of American Art. Shoppers will also be able to pick up a limited edition Balloon Dog bag for $49.50 (not a bad deal, as Forbes notes, because Koons’ real 12ft (4m) high balloon dog sculpture sold for $58.4 million). As a side note, Koons is everywhere in Manhattan this summer – he also has a massive living sculpture called Split-Rocker on show outdoors at Rockefeller Center. The theme of the takeover is Fashion Loves Art and it’s an amazing collaboration in a long line of value retailer/designer partnerships that started with Target and Alessi design guru, Michael Graves, in 1997. H&M picked up on it in 1994, working over the years with everyone from Karl Lagerfeld to Beyonce. The H&M/Koons tie up to me is the most inventive collaboration yet. It’s the innate contradiction that makes it interesting – fast fashion contrasted with fabulous (albeit populist) art. This caught my attention this week, because I have been working with Michael Sussman, chief of Y&R’s Brand Asset Valuator, on a presentation about ‘retail tensity’. As Sussman refers to it, the concept of tensity is a “perceptual paradox”, combining things that don’t normally fit together. The most famous example is Target in the US, which has built its reputation on cheap chic.  I think tensity is a very powerful notion in retail, particularly at a time when the shopper has so many options and has to fight just to be considered. Tensity is most evident in value retail. As another example, Costco sells what it call ‘triggers’, like bulk laundry detergent for a bargain price, but counterpoints the basics with ‘treasures’, like $21,000 diamond rings. You also see tensity in other retail propositions. Patagonia achieves its tensity by asking shoppers to consume less (its famous ad was headlined Don’t Buy This Jacket), and they even merchandise Worn Wear – second hand, restored Patagonia product. Online menswear retailer, Bonobos,  has ‘guide shops’ where you can’t buy anything – come in, try on, then buy online in the store or afterwards. A caviar vending machine I saw in Westfield Topanga (an LA shopping mall) also embraced tensity, delivering a luxury item in a functional, but fun way. Now more than ever, we can’t bore people into buying. There needs to be a level of tension, a tensity, to make retail interesting and compelling. The six-story balloon dog on Fifth Avenue did it for me. What’s your retail tensity? Jon Bird is MD, global of Labstore, Y&R’s worldwide retail and shopper marketing network.
