Kate and Laura Mulleavy are fashion rock stars. Since launching their line, Rodarte, in 2005, the sisters have won countless awards (including the CFDA Womenswear Designer of the Year Award, the Cooper Hewitt National Design Award for fashion and a National Arts Award), have had their pieces exhibited in museums such as the Costume Institute at the Metropolitan Museum of Art in New York, created collaborative lines with everyone from Opening Ceremony to Target, designed costumes for performance from Het National Ballet in Amsterdam to the Oscar-winning film “Black Swan,” and have consistently landed their line on Top 10 lists in Vogue and Women’s Wear Daily. And that’s barely scratching the surface.

This week: Garmenteur’s new stationery collection, Samantha Goldberg’s One of One line, The Green City Market’s outdoors and Virgin Atlantic’s very own shade of lipstick (above).

This week, we spy: Neiman Marcus’ Gift of Scent, an Andrew Gn trunk show, Garnier’s Pop-Up Mobile Salon tour and Bluemercury’s newest location.

Chicago’s most fashionable ladies are embracing the warmer weather with flirty, form-flattering bell dresses. While our black-tie galas are still dominated by floor-length gowns, less-formal affairs are the perfect time for this cuter cut, with a hemline that hits between mid-thigh and knee.

Three local startups are ushering fashion into the future.

This week: Coach + Step Up Women’s Network, Lana Jewelry, new Korres lip butters and Tavi Gevinson in “Cadaver”.

This week: a “STARK”-raving sale, Yvel at C.D. Peacock and The Land of Nod.

Fashion is taking a comfortable turn as slouching, tapered trousers have become a mainstay. Far from the MC Hammer pants and Zubaz of the ‘90s, these slick slacks are cut to avoid billowing at the hips for a silhouette that’s flattering on almost any body type.

For the last 20 years, Amsterdam-based fashion house Viktor & Rolf has been one of the most innovative lines in the industry. Designers Viktor Horsting (above, right) and Rolf Snoeren are known for creating ready-to-wear garments that double as works of art, producing theatrical runway shows and crafting the popular Flowerbomb perfume — then turning around and producing one-off collections for H&M and Samsonite. To honor the designers, Ikram and Josh Goldman, the duo behind noted boutique Ikram, held a dinner in the shop’s second floor café. (Read more about the event here.) There, Viktor and Rolf answered a few questions about their new collection, their creative process and reaching the 20-year milestone.

It’s seems unlikely that a Spaniard and a New Zealander, both based in New York, could come together and design clothing that is so utterly Chicagoan. Yet that’s exactly what Michael and Nicole Colovos have done with Helmut Lang, the line they took over after Mr. Lang stepped down in 2005.
