A crisp white and black palette, lean silhouettes, and perforated details took the runway for Tibi's Spring lineup — in short, it's the skilled balance of street-chic and contemporary polish that Amy Smilovic does so well. Picking up where she left us for Fall, Smilovic continued to redefine the classics with cool, contemporary fits — lean pencil skirts, boxy tops, midriff-baring crop tops, and low-slung, cropped trousers. But where Fall gave us a more menswear-inspired riff, this collection gives way to more femininity with fit-and-flare silhouettes, waists cinched in with wide leather, corset-style belts, peplum, and a touch of pink. There's no trick in this kind of simplified dressing; but there are special details — geometric, kaleidoscope-inspired prints or subtle perforated effects that elevate clean shift dresses and tops.

• Trends: Leather, perforated details, peplum, colorblocking, kaleidoscope prints.
• Colors: Black, white, yellow, pink, and khaki.
• Key Piece: The black perforated pencil skirt and sleeveless top with wide leather belt.
• Accessories: Cutout heels, ankle-strap heels.
• Who Should Wear It: We'll see it on front-row fixture Olivia Palermo, but Miranda Kerr could easily wear any of these impeccably chic separates.

It may have been pouring outside, but inside at Altuzarra's show, we were transported far from the storm to a beautiful place, where classical music serenaded the crowd and front-row attendees Kate Bosworth, Anna Dello Russo, and Nina Garcia, and models made their way down the catwalk in up-to-the-neck fringe, embellishment, and knee-high gladiator boots (that we're betting Dello Russo was mentally adding to her Spring shopping list). To say that the stakes were high for the CFDA award-winner (in a room packed with the fashion elite) would be a serious understatement. Those expectations were palpable as the lights faded, but with the designer's first look (a cape paired with a pin-striped button-down and slim skirt and a pair of knee-high statement sandal-boots), it was clear he would deliver everything — and more than — the crowd was hoping for. There were hushed gasps, first over the stunning shoes, then more as the lineup turned from structured and sophisticated menswear-infused jackets and trousers and lean, closely-fitted skirts to a more exotic exploration in draped, fringed, and embroidered skirts and tops layered with tassels that felt all at once regal and wanderlust-inspired. Throughout, there was a sense of both the opulent sophisticate and the world-traveled gypsy: rich fabrications and gold accents — and did we mention the shoes? — all added up to Altuzarra's fantasy-inducing Spring.

• Trends: Fringe, draping, capes, slits.
• Colors: Gold, blue, white, neutral shades of gray, tan, and olive, and floral print.
• Key Piece: It may just be the drama-inducing footwear.
• Accessories: Statement gladiator boots and open-toe knee-high boots.
• Who Should Wear It: Cate Blanchett, Taylor Tomasi Hill, Zoe Saldana, Kate Bosworth, and Gwyneth Paltrow could all carry it off.

Alexander Wang always has something up his sleeve, and Spring '13 didn't disappoint. Looking beyond the horizon, the boy wonder produced a sporty, futuristic lineup of skin-baring cutout dresses, metallic bombers, and a lot of leather. Oversize, structured cuts dominated Wang's athletic mood — we couldn't take our eyes off the white rubberized twill parka — lending an intrinsically new-age aesthetic, further exemplified through laser-cut, fish line, rubber, and mesh details. Also to note were the sexy, liquid metallic knits paired up with croc-embossed skirts. Wang's seasonal zinger? As the lights went off at the end of the show, models stood statuesque as Wang's collection came to glow-in-the-dark life. Suffice to say, the crowd went wild. Welcome to the future, people.

• Trends: Leather, crop tops, sheer details, cutouts, futuristic fabrics.
• Colors: Black, white, metallic silver, tan.
• Key Piece: The white rubberized twill parka and sheer paneled dress looked amazing.
• Accessories: Strappy boot sandals, boxy woven bags, plastic baseball helmets.
• Who Should Wear It: This collection isn't for the wallflower. Lady Gaga, Rihanna, and daring top models like Hanne Gaby Odiele.
