They've been really popular the last couple of years for little girls. I love them. Love them because they bring new life to outgrown tights.
I find it painful to toss really cute tights, and I don't anymore. Now you don't have to either.
If that ends up being the case just use a little piece of cotton lycra or stretchy interlock or rib knit. Cut a strip the width of the bottom of your tights X 2. Sew the ends into a tube and you will have what I have in this photo. I'm just going to use the middle piece and I normally cut 1.5 inches wide.
My 6 yr old says these are cool, and the tights with feet are for little girls. I thought she was a little girl?
Too bad little miss lives somewhere where we just can't wear these during the winter.
She'll be wearing these ones on Valentine's day though. All in the name of fashion.
If you'd like to make the dress...
