Although coins are still used as sequins in some cultures, modern sequins tend to be made of plastic. They may also be referred to as spangles, paillettes, or diamantes. Paillettes themselves are commonly very large and flat. Sequins may be stitched flat to the fabric, so that they do not move, and are less likely to fall off； or they may be stitched at only one point, so that they dangle and move easily, to catch more light. Some sequins are made with facets, to increase their reflective ability.

从这里的解释可以肯定，使用sequin不会错，而且还有别的说法。有时，在査找单词的时候，会发现意想不到的线索。比如，査“廓形”的说法，发现百度百科有一篇标题为“廓形”的词条，其中提到：

克莉斯汀•迪奥曾在50年代推出一系列字母造型时装，分别用A、H、 Y等英文大写字母来比拟他作品的廓形。

顺藤摸瓜，査到“克莉斯汀•迪奥”的英文说法Christian Dior,再査找这个人的简历，看到：

In the 11 years before his death, Dior dictated European style. Each of his collections had a theme 一 the classic suit, the ballerina skirt and the H, A and Y lines that ruled the early 1950's.

再利用这些关键词去核实:

Figure 4-15. Between 1954 and 1955, Dior introduced his alphabet lines: the H Line, the A line, and the Y Line. The H Line was characterized by the controversial Tudor bodice and dropped waistline of the middy. The triangular A Line of 1955 was a huge success and has remained a constant silhouette of fashion ever since. The Y Line did not translate as easlity into American ready-to- wear versions. Basically it was a slender body with a top-heavy Y look. Some versions were inverted, with a slender top teading to a Y bottom profile.

现在发现，前面推测和查证的A-shape Y-shape等说法并不正宗。到此 为止，我们找到了各种造型的祖宗，可以确信无疑地说：A字造型就是A Line. 百度百科同一篇文章还提醒我们“廓形”、“款式”的区别：
