LOS ANGELES ( TheStreet) -- The arrival of spring brings a lineup of fashion essentials that will make their way into national retailers and into the closets of America's most stylish men.From head to toe, men's style for spring/summer 2010 is about feeling good, translated through more colorful fabrics in more comfortable cuts, all in styles that have evolved over the previous few fashion seasons. Men's suits become less snug for summer, a blessing for anyone who's ever had the issue of a tight pair of wool pants on an unfashionably humid summer day. Definitely not baggy, trousers are more liberal in cut for Gucci's collection by Frida Giannini of bold blues and tropical white suits often hemmed to show off a bare ankle in a lace-up dress shoe or colorfully trimmed loafer. In Paris, Lanvin's Alber Elbaz played with a higher waist and more generous inseam for its suits with defined shoulders and darker, monotone silhouettes and muted neutrals. Those looking for a more casual look or trying to find the perfect Friday business ensemble should keep their colors limited to khaki and white for new summer fashion acquisitions. Calvin Klein Menswear by Francisco Costa showed off its ability to play up various shades of creamy beige and browns for ultra-thin fabrics for trousers and two-button blazers accented by the occasional pop of Army green or white. Dolce & Gabbana took the look even darker with a dressy version of Indiana Jones marked by a six-button desert-brown vest under a tapered blazer with wide-pointed label and chunky boots. Dress shirts should express your attitude -- like Michael Bastian's striped-white button-down with solid gray collar worn with a navy blue tie with stop-sign red detailing. Dolce & Gabbana kept it Italian with white, wide-collared dress shirts under skinny black ties or a simple button-down long sleeve cotton pullover under a classic blazer. Others simply ditched the shirt altogether with oatmeal gray, black or solid white T-shirts under suits by Calvin Klein and Michael Kors, reminiscent of "Miami Vice" meets Sao Paulo nights. The weekend shirt that in previous years included such hot trends as the gingham and plaid gets a more western vibe with Chambray, which GQ even touted as the official "shirt of 2010 summer." Rag & Bone further interpreted the trend through a simple military jacket with band-collar and elongated sleeves for crisp spring nights. Our favorite shirt, however, is the incredibly affordable H&M summer classic with a pair of contrasting denim pants that retails for under $20 and is possibly the cheapest find of the season.
