I've been reading and watching a bunch of stuff on how to tell, but I'm still having such a hard time! Pretty confused. I also have two books on order. A lot of vintage inspired modern stuff looks vintage, so that messes with me. So it's hard to tell by era styles. Particularly recreated 80's looks. I only knew they weren't from the 80's bc the tags said Charlotte Russe. Other problems are that a tag will be hard and crispy, with no dry cleaning mentioned on it, and made in USA, but then it'll have a plastic zipper. Plus they had plastic zippers since the 60's or mid 70's. Modern also has covered buttons and reinforced button holes, and also flat lining. Or a dress will have a metal, utility looking zipper (including teeth), but then some seams will have overlock stitching. And I don't understand why overlock stitch would negate it being vintage if a serger machine was invented in the 1800's. Hidden zippers are also a modern thing. Sewing machines were being used for a long time, so why would hand sewn indicate vintage? Modern tags also have large, stiff, embroidered tags. Why would vintage only have hand embroidered tags? They had machines for a while. Also, wouldn't it be really easy to create a stamp for labels? I've read that labels with print (except for union labels) mean that it's not vintage. So, I found a skirt with hand stitching. No tag. Thin fabric. But it could just be modern handmade. How do you know? I found a dress with a fully metal zipper, and it looked kind of industrial, down the back, but then the tag didn't look vintage. I think. I'm not even sure. I do look in the guild's tag database, but they don't have a full list. And it's not like I can return things for my $ back. I'm ending up wasting a lot of money and time and effort. Unfortunately, I have a very limited income (mistakes are very expensive to me) and am just starting out. I was hoping I could reinvest profit back into my hobby/selling. Any advice?
