I love the garter look for tights! But it can be really hard to find awesome tights in anything but the dreaded one size fits most. :( You should be able to at least pick a different size!
So I found a really great website for pretty tights with all kinds of sizes (usually up to 4X)!
Donatellas is a UK based company that offers really affordable tights with tons of cute styles! Most options are under $18 and I believe all the shipping is free as well - aw yeah!
These are perfect for a gyaru wardrobe! Wear any of these under some shorts or a skirt to look really great. Go check it out! http://www.donatellas.com/tights.html
