Seriously, you will be surrounded by drifts of cotton wool in your bathroom, crying with frustration and acetone fumes as you waste 45mins of your life trying to get the damn stuff off. The polish part dissolves, leaving the now colourless glitter seemingly attached to your nails with super-glue. [DO NOT be tempted to avoid nail polish remover altogether and pick it off in chunks using your teeth whilst watching Gossip Girl, men inexplicably seem to find this an unattractive trait. Also, it's not something you want to be ingesting].
Anyway, all you need is that same cotton wool and polish remover*, but you want to soak a separate piece for each nail. Position each bit of cotton wool onto the nail, and then secure it with a strip of tinfoil folded into a parcel around your fingertip. Watch some telly for 10 minutes, and then remove the foil and cotton wool from your first nail, by firmly pressing down on the foil and twisting the cotton wool over the nail as you go. You'll find that the polish comes off pretty much entirely in one go, and any glitter left at the edges is no longer welded on, but can be simply wiped off.
