技巧1：了解自己的尺码
在网上购物的基本条件，就是自己必须非常清楚了解自己的尺码。身高、体重、肩宽、胸围、腰围、臀围、袖长，这一整套的数据必须先熟记。最好到裁缝店让裁缝帮量一量，找不到裁缝店自己买一软尺量也行，这样才能根据网上提供的服装尺寸，了解自己到底能不能穿。碰见好的掌柜，把这套数据一说，掌柜的自然会告诉你衣服于你是否合适。
技巧2：看清产品的照片
买服装,我只看实物拍摄的那些产品照片。因为经过处理过的图片,美轮美奂的照片,是无法看清产品的真面目的。其次,如果产品还有很多的细节图,就能更进一步的了解产品是否符合自己的需要。
技巧3：分辨店铺的信用
现在的网店，都会按信用分级。有些信用排比很高的店铺，不见得就真是物有所值。因为信用有可能作假的。我一定要看所有顾客的评价。如果店铺里大部分评价都只是好评，而且只是喊好，但没有具体评价语言，那么这个信用度可能就含有水分。但如果很多买家对掌柜有详细的留言，可信度就比较高。而且从一些买家的留言就能看出掌柜的与买家之间的感情。
技巧4：体会掌柜的态度
在网上购物，掌柜的服务是非常重要的。不只是服务态度好，而是掌柜是不是真心对待顾客，还是只是为了销售。有时候碰见好的掌柜,你将自己的尺寸告诉对方, 对方会客观地告诉你这件衣服你穿不合适,那么恭喜你,这样的掌柜绝对是认真负责的人, 不是为了销售而销售,不理顾客死活的主。
技巧5：观察别人的纪录
在网上购物还有一个很重要的参照指数,就是别的“钻石买家”的纪录。如果你看中的东西,有别的钻石买家买过,那么说明那人的品位和你接近,看看她的购物纪录,了解她都买过什么东西,在哪些店铺消费,会对自己的购物大有帮助。
技巧6：看好店铺的介绍
在网上购物,有的店铺接受退换货,有的店铺不接受，具体就要看每个掌柜自定的规定了。为了保护自己,先看好店铺的规定,衡量自己能够接受的底线,是很重要的。
