>> Karl Lagerfeld's 45-piece limited-edition collection for Macy's hits 235 of the retailer's stores and online later this month — on Aug. 31 — and finally, there's a look at more than just one dress from the line. The collection, which runs $50 to $170, stays much within Lagerfeld's designing comfort zone — lots of black and white with pops of pink, lots of high collars, several pieces showing off imagery of the designer himself. The full collection — plus a peek at the ad campaign, featuring Coco Rocha — in the slideshow.

>> The "Alexander McQueen: Savage Beauty" exhibit may soon be coming to a close, but his designs — including more than 24 garments that have never before been displayed — will be on view when the Daphne Guinness exhibit opens on Sept. 16 at New York's FIT Museum.

The showcase, which Guinness co-curated, encompasses over 100 garments and accessories from Guinness's personal collection, plus films and images of and by her. She describes herself "not [as] a muse," but more like "a bee," going from one designer to another — which explains the wide array of McQueen, Alaia, Tom Ford, Dolce & Gabbana, Rick Owens, Gareth Pugh, plus couture from Chanel, Dior, Givenchy, Lacroix, and Valentino, and clothes Guinness designed herself, that will be on display.

The exhibition will be designed with Guinness's New York apartment as inspiration, and will also include her collection of Philip Treacy hats, Shaun Leane “armor” jewelry, and the vertiginous platform shoes custom-made for her by Christian Louboutin and Noritaka Tatehana. A preview of the Guinness's pieces showcased in the exhibit, in the slideshow.

>> Fresh off the news that its launching US e-commerce next month, Zara has released its Fall 2011 ad campaigns. Stella Tennant returns as face of the brand, shot by David Sims in the main collection's dark, masculine silhouettes, while Hailey Clauson models a brighter selection of pea coats and miniskirts from the retailer's TRF range.

>> Gareth Pugh doesn't currently participate in couture, but he recently took a crack at a showstopping bridal gown — for his best friend and longtime collaborator, stylist Katie Shillingford, who was married last Friday. Shillingford wed Alex Dromgoole in the 1930s Art Deco-style Eltham Palace of Greenwich, England, wearing a custom pale grey slashed chiffon Pugh dress, complete with a trail that hung from her shoulders and a veil created by Stephen Jones.

Shillingford's bridesmaids — including Dazed & Confused and Another's Karen Langley, who helped design the wedding cake — wore black striped knitted dresses by Craig Lawrence, and Shillingford changed in a Fall 2011 Gareth Pugh gold dress and Fall 2011 Miu Miu shoes for the reception.
