How to shave bikini line before laser?

[schmalex]

I've always had Hollywood waxes in the past but have decided to take the plunge and get my bikini line lasered. I need to shave 24hrs beforehand but I've never shaved my bikini line before. How on earth do I do the underneath bit and bum?! 😱
Any tips, wise mumsnetters?

You need a mirror, a phone torch, a five blade razor and an eyebrow razor for some of the more delicate bits. Good luck!

That's not bikini line is it, that's the whole area.
