In the past I've been guilty to wearing vibrant and crazy shades of lipstick. With my pale skin and blue eyes, wearing a plum lipstick was a big no no. Having some advice from my mam (a professional MUA) I can now confidently choose the perfect shade for my colouring.
For an everyday lipstick, choose a shade 2 shades lighter or darker to your own natural lip colour. My everyday lipstick is Please Me by MAC.
Try out the lipstick before you buy it. Ask the make up artist on the counter to put it on you (with a brush for hygiene reasons) so you can see how it actually looks on you rather than guessing or sampling on your hand.
Lip liners. This is the biggest sin of all. Weird contrasting lip liners - don't do it. If you require a lip liner you must match the shade exactly. I like to use a brush to line the lips with the lipstick, that way it will always be an exact match.
If in doubt when choosing a dramatic lip colour - go red. Everyone suits a standard brick red. My favourite is Ruby Woo by MAC. This is matte and you won't even need to line your lips as its so easy to apply!
To make your colour last all day apply a quick coat of Lipcote. If you're wearing a matte lipstick it can ruin the texture of it, but for a satin look it works perfectly. Make sure it fully dries before you close your mouth and make sure it coats all the way round your lips. I can have a cuppa and my lunch and it still powers on!
And the most important rule - of all lips or eyes. This is just as important as the legs or bust rule! Choose one, don't go overboard with both or you'll risk looking like a clown. If I'm doing dramatic eyes I'll stick to a nude/everyday lipstick or just a coat of lipgloss. With a bold lip colour I stick to some simple shadowing.
