This is not a refashion, really. It is more of a recipe how to fix all those t-shirts which were mangled in the process of removing those annoying tags.
I have dyed this t shirt only to notice the holes left from removing the tag. To conceal the holes, I added a piece of decorative tape stitching it over to cover the the tears.
Now it looks like an intentional and fun detail!
Hope you find this garment fixation idea useful!
