Nothing says vintage like seamed stockings. When stockings were first available, they had seams because manufacturers needed them. After equipment improved to eliminate that need, seams disappeared. Wearing seamed stockings now is like waving the vintage flag.
I found an online store that sells seamed stockings and other vintage lingerie. Their wares are fun to browse. The store is called What Katie Did.
I bought a pair of seamed stockings and some long silk gloves. Here are some shots. Let me know what you think.
