Mizzthingaling Awesome! I'll give you my shades. I haven't worn MAC foundations in a while so I think NC45 might be my darkest summer colour.
I use the MUFE HD Invisible Color in 350. It's super peachy and I bought it for correcting my undereye area.
I also have the Nars Creamy Concealer in Biscuit and the Laura Mercier Secret Camouflage in SC-6. They don't match my skin 100% but they still do a pretty good job. All three are different textures which makes it great for different concealing jobs. Under my eyes I use the MUFE and then Nars and for blemishes or bigger areas, I'll mix the Laura Mercier colours with my foundation.
This girl is pretty spot on my shade and she has amazing recommendations: http://www.missbeautyadikt.co.uk/


I do wear soft contact lenses and they do not hurt or irritate at all.
