That's how mine worked, too.
Oh, if you do sell it, don't forget about the actual vest part- you will need to order one for whomever you sell it to (since they are free to the "owner" <img src="i/expressions/face-icon-small-wink.gif" border="0"> ). Hopefully, they will be really close to your size, or else they may have to buy a vest anyways ("Yes, I know I have been ordering an adult medium, but now I need a child small" might sound a bit odd <img src="i/expressions/face-icon-small-wink.gif" border="0"> ...lol).
