Your morning fashion and beauty report: Katy Perry spoofs 'Sesame Street' flap. Lady Gaga good for Armani. Miranda Kerr dazzles at Milan Fashion Week.

 

Katy Perry was on "Saturday Night Live" over the weekend, singing, of course, but also spoofing the tempest in a teapot over the low-cut top she wore on a "Sesame Street" taping that got her segment cut from that show after it showed up in advance on YouTube and led to parental complaints.  This time she wore a really low-cut Elmo T-shirt and played a children's library volunteer in trouble over her revealing clothing. She didn't say much; instead, she just let her tee and her costars do the talking. [Entertainment Weekly] 

Topshop, that British shrine to fast fashion, is moving west, with plans to open its second U.S. store (the first is in New York) on Chicago's Michigan Avenue in late spring. Can L.A. be far behind, we wonder? [WWD] (Subscription required.)

Target, our favorite big box store, is thinking outside the box with a new box: the retail giant plans to open 10 much, much smaller "urban footprint" stores, with one of the first to be near Seattle's Pike Place Market. [Boston Globe]

Giorgio Armani's partnership with Lady Gaga (costumes for the "Alejandro" video, the crystal-encrusted, orbiting hoops dress she wore to the Grammys, etc.) is breathing a new creative spirit into the design firm. [Wall Street Journal]  

Model Miranda Kerr, accompanied by husband Orlando Bloom, partied at Milan Fashion Week in a stunning fringed LBD, so short it gave new meaning to the word "mini" and cut to the waist in the back. She proved that being five months pregnant doesn't mean you have to stop wearing glamorous, sexy styles. [FabSugar]

Calvin Klein is building on the success of its CK One fragrance and plans to turn it into a "lifestyle" brand offeing jeans, underwear and swimwear designed to appeal to a younger crowd. [Vogue UK]

Catherine Walker, who designed more than 1,000 outfits for Britain's Princess Diana, including the black dress in which she was buried, has passed away at age 65 of breast cancer. [Catwalk Queen]
