These are the bases I am currently jumping between at the moment.
Giorgio Armani Face Fabric - this looks quite dark but shade 2 was too pale for me. A fab product it melts into the skin leaving a flawless face. Its got a really lovely gel like texture. It's good if you just want a light base. Retails at £30 for 40ml.
Giorgio Armani Luminous Silk Foundation - shade 5 - an oil free fluid with a silky texture and the ability to build on colour. I'm just about running out of this one and I'd definitely re-purchase.
Clinique Moisture Surge Tinted Moisturiser with SPF 15 - shade 3 - love this if I just want a bit of colour, very moisturising and gives a natural tone.
BareMinerals Original SPF 15 Foundation - light - really love this, easy to use and can build up coverage. BareMinerals also has a brilliant starter set which is a great introduction to this brand.
What do you use? I'm always looking for suggestions for foundations.
