This Thursday, head to Saks Men's Store to preview four incredible Fall 2011 collections:  Kenzo, Haversack, Pringle of Scotland, and Viktor & Rolf. Aside from informal modeling, the evening will also include shopping, DJed tunes and light refreshments. Here's our breadown of the collections.

Kenzo

Kenzo's Fall 2011 collection is the brand's last collection led by designer Antonio Marras, and he certainly left on a high note. Expect plenty of plaids, and patterned knitwear, with a few touches of plush velvet and leather. The overall collection is very dapper, with tight layers, but has a nice edge, too. For color, traditional black pieces are mixed with pops of autumn leaf tones, while fits range from traditional tailored suits to very old-school, high-waisted trousers. The line now welcomes Opening Ceremony founders Humberto Leon and Carol Lim as the new creative directors.

Haversack

The cult-worshipped Japanese label, founded in 1997, was named after the standard-issue US Army bag that's a symbol of strength and durability. The label has a quirky-vintage feel, and a more prim and proper than rugged-army aesthetic. The Fall 2011 collection is no different. Most notably, the collection features fun, colorful tweeds paired with bowties, a lovely men's poncho, and cuffed, capri-length trousers. Fits are precise with bold looks and plenty of attention to details. 

Pringle of Scotland 

Pringle of Scotland is the historic label that coined the term "knitwear" and invented the argyle pattern. In the Fall 2011 collection, designer Clare Waight Keller (in her last collection for PoS), stayed true to the label's British roots. Each complete look is features an incredible wealth of texture. The chunky knitwear and dramatic outwear really stand out in the collection, which also incorporates beautiful patterns and leather. The leather details are truly beautifully, creating such a nice contrast. The slouchy pants are equally intriguing, creating perfectly rugged, complete look. Basically, we're in love with the whole collection. 

Viktor & Rolf

The Amsterdam-based fashion house of designers, Viktor Horsting and Rolf Snoeren, is notorious for their theatrical, flamboyant design. The menswear line, "Monsieur" was added in 2003, and is actually more scaled back. The Fall 2011 collection is sharp with plenty of modern suiting. The outwear ranges from thick, black leather shearling jackets, to modern, well-layered wool peacoats, both in a variety of lengths. A majority of the collection is in grayscale, with a bit of winter tan and a few plaids thrown in for good measure.
