I opted for SS021 Syntho Blending Fluff, SS004 Deluxe Oval Concealer and C406 Large Duo Fibre Face Brush.
SS021 Syntho Blending Fluff:
The one thing i really struggled with when applying with my fingers was blending eyeshadow in my crease. This brush allows me to do it effortlessly and is great for creating the smokey eye effect. Buy (here) for £4.99.
C406 Large Duo Fibre Face Brush:
I've heard some great stuff about duo fibre brushes and this brush definitely didn't dissapoint. It blended my foundation in really well leaving a natural finish. This is much cheaper than most duo fibre brushes on the market and just as good, if not better. Buy for £9.29 (here).
SS004 Deluxe Oval Concealer:
I've always found that applying with your ring finger i can sometimes use too much concealer and end up with a really "fake" finish. This brush allowed for a natural wide eyed look to be created and evenly distributes the product around your eyes. Buy for £5.49 (here).
