I've managed to narrow my bottle shape down to two options. I made the decision based on the type of bottles I look for when Im buying a new product, I look for convenience and the ability to control the amount of product I use.
While deciding which colour combination to use, I had to think about what I wanted the product to say and the kind of people I wanted to be able to relate to it. I wanted quite powerful and feminine colours without making the product look girly or childish. I also played with the idea of using patterns but felt it might take away from text on the bottle.
