If it ain't broke, don't fix it. Narciso Rodriguez's Spring 2013 collection was one of the most critically acclaimed of his career, so it's only natural that he would revisit its themes and successes for Pre-Fall.

This offering used the same triangle motif found in Rodriguez's last outing, but this time it appeared as a sort of downward-facing tuxedo stripe on cropped trousers or as a chevron-shaped seam on a few dresses. There was sparkle, too, thanks to beads judiciously applied to a blood-red tunic and a vermillion cocktail dress. Speaking of colors, some of the Spring palette bled through here. Much of Pre-Fall stuck to black and white, but there was rust and orange dotted here and there, and even pale pink on an oversize clutch.

What's new, though, was Rodriguez's expanding use of knits and leather. The colorblocked sweaters in this collection are sure to be crowd-pleasers when the Pre-Fall deliveries make it to stores, and so will a deep-red sheath in calfskin.

Move over Kate, Mango's got a new leading lady. After two seasons with Moss as its face, the Spanish retailer has named Victoria's Secret Angel Miranda Kerr as the star of its upcoming Spring 2013 campaign. The campaign, which includes the whole shebang — television, billboards, online media, and print — was shot by Inez van Lamsweerde and Vinoodh Matadin in New York and has finally been unveiled for your viewing pleasure.

Kerr joins quite a crew: in addition to Moss, Milla Jovovich, Naomi Campbell, Eva Herzigova, Karolina Kurkova, Claudia Schiffer, Christy Turlington, and Isabeli Fontana have all posed for the brand.

Peep Kerr's Mango campaign images — plus get a look behind the scenes at the shoot — right here.

There's a distinctly Southwestern flair in Scott Sternberg's Pre-Fall 2013 collection for Band of Outsiders. It makes sense: the designer credited a trip to The Lightning Field, artist Walter De Maria's installation of some 400 lightning rods in the desert of western New Mexico, as what inspired the offering.

The feeling shines through in a number of the collection's dresses and shirts, which feature prints that call to mind Aztec motifs and Navajo blankets. Sternberg even worked a new geometry into one of his bandage skirts, coloring the layers so that they looked like steps.

From there the collection touched two other points of interest for Sternberg: suits paired with shirts were layered over sweaters with a BOY monogram in a nod to his preppy underpinnings, while a series of all-black looks (two of which featured bandage tops) veered off toward eveningwear.

The concept of men's uniforms — those worn in the boardroom, on the battlefield, and at the ballpark — inspired Reed Krakoff to create a masculine Pre-Fall 2013 offering freshened up with feminine details.

"I wanted to figure out a way to take the things you would normally find in a man's wardrobe and make them fresh and feminine," he said. To that end, the designer turned men's suits into boxy blazers, coats, and slim trousers for day wear. Skirts often came with asymmetrical hems and were paired with luxurious tops like a v-neck sweater vest in mink and cashmere or oversize raglan sweaters. Texture was just as important here as shape: Krakoff cut a bomber jacket from shearling, for example, and printed the pony hair of a topcoat to look like snakeskin. A lace t-shirt dress would have been a little out of place here, but dipping it in black rubber made it stand up to the other strong pieces in this collection.

A day before he presented his Pre-Fall 2013 collection to editors and buyers, Jason Wu posted a photo of "Martha Hunt giving Jerry Hall realness" to Instagram. If Hunt was busy channeling that queen of '70s glamour and seduction during the lookbook shoot for this offering, it's because that's the feeling Wu was after.

Extending the unexpectedly sexy tone of his Spring 2013 collection, Wu created a luxuriously worked collection of dresses and gowns that captured the liberated spirit of the decade. The sheer chevron panels on his evening gowns, for example, alternated with wide swaths of sequins that kept the wearer covered up. Elsewhere the sex appeal toughed up, with dresses and slim trousers in leather (or a graphic black, white, and yellow eel skin pattern) and belts accented by chain-link hardware.

Keds is celebrating the 20th anniversary of Kate Spade New York with a capsule made in preppy-pep heaven. Gingham, polka dots, chevron, and nautical stripes adorn Keds's classic canvas sneaker silhouettes and come in snappy hues such as orange, blue, and bubblegum pink.

"There is a fun whimsical aspect to [Kate Spade] and it relates to Keds," explained Stephanie Brocoum, Keds VP of marketing. "[The shoes] are right in that sweet spot of everything feminine, fashionable, versatile." Ranging from $75 to $85, the collection will hit keds.com and Nordstrom.com, as well as Kate Spade New York and Nordstrom stores, in February. Peep them all here.

UK bauble brand Mawi has teamed with Italian heritage house Bruno Magli on a Pre-Fall 2013 capsule brimming with sparkle and shine. The seven-piece collection includes a jewel-adorned clutch, several vibrantly hued baubles, and a selection of Magli's signature pumps in rich gem tones and leopard print.

While all are gorgeous, perhaps the most enticing part of the collaboration is that it strikes a perfect balance between sophistication (Bruno Magli) and youth (Mawi). "It was about infusing a good dose of lots of different things — the classic side, the chic side, the elegant side, and the edgy side," Bruno Magli creative director Max Kibardin explained. "Even though there's still a lot going on, it still has an overall minimal, clean look."

Priced from $300 to $1,875, look for pieces online at BrunoMagli.com this Spring. Until then, you can preview them all right here, now.
