West Bridgewater, Mass.,-based metrostyle has released some of the upcoming bathing suit trends for summer, 2008.

Tankinis, which were so huge last year, are still popular, while geometric shapes and mix-and-match skirt or brief bottoms are looking popular this season.

Halters and swim dresses are popular. Halters get rid of some of your back tan lines, while the dresses offer a more modest approach.

metrostyle has a lot of high-cut bottoms that they’re showing off. I don’t think this trend will hold up. It gives a high tan line that’s above the waist and gives younger women an aged look. It’s not very flattering, but it’s gaining popularity among some women.

Our friends at Ujena are coming out with some sexy halters, especially their belted leopard bikini ($79) and a startlingly sexy ruffled polka dot thong set ($69).

Metallics are also looking to have a big year — shiny silver and gold will dazzle with the beach sun.
