Boho Chic

A style of fashion that become very popular in the 1990’s, drawing from hippie countercultural influences of the 1960’s. Boho references bohemian, the lifestyle, not the ethnicity. It’s casual, relaxed, romantic. Boho chic draws on prints, laces, florals and mixing prints and laces together in a many-layered blend of casual and romantic fashion, a floral gown with handmade lace edges and collar with a pair of work boots and a heavy cardigan for example. Ethnic-inspired jewelry, shoes and accessories are often important elements in boho chic styling.

Boat Neckline

A boat neck, also called a bateau neck or Sabrina neckline, is a wide, high neckline that runs horizontally, front and back, almost to the shoulder points, across the collarbone. For no real reason other than one sounds casual and the other sounds dressy, people are more likely to use boat neckline for casual tops and bateau neckline for cocktail and formal gowns. The Sabrina neckline usually has a little bow on each shoulder where they connect.
