I heard about these palettes from my favourite beauty bloggers and some new ones I never knew of. Not to mention Sleeks marketing team that make good use of twitter. When I first saw the palettes I was unsure if i would purchase both. I tweet often when a new palette comes out that i do not need it. 
The Bad Girl palette reminds me of the Smokey Eye palette. The colours are different but not so different that it was a must buy. The Good Girl palette is the most original for me. Just full of pretty varying shades of pinks, corals and light reds. It is missing a truly darker contouring shade but not really missed. Especially if like me you most of the palettes Sleek have released. 
I have worn looks from both palettes to work and got compliments all day long. When I wear shades from Bad girl many colleagues ask me if I am going on a date after work with hubby. Whilst Good girl tends to bring compliments on how vivid the colour shows up. Both palettes are packed full of pigment and worth every penny.
I would have waited until the 50% one day sale Sleek Makeup are having on the 11th November but I just know the website will crash. Sleek have some serious stan fans of their products. I will just wait for the natural/nude palette that via twitter they told me will be out soon.
