I used to love G's, it was all I wore until I had kids then flossing became very uncomfy - damn you hemorrhoids! I think I've worn a G once since having DD1 and it drove me nuts, so annoying!

So these days I wear very comfy little numbers by Holeproof. They're seamless and don't ride up at all. I just love them. I generally buy mine at David Jones when they're on sale.

I recently bought some bamboo low cut briefs from Target (from the Target Essentials range) and they're lovely too and cheap!
