I am a huge fan of Sigma brushes (trust me this is relevant) and their F80 brush is world renowned for being one of the best rated Kabuki brushes. I tend to agree. I had heard Shannon (Shaaanxo, XO Beauty founder!) say that she wanted her brushes to be the quality of a Sigma brush without the price tag. This lead me to ordering this brush for comparison and I set my expectations high! For reference, the Sigma will set you back around $50 and the XO Beauty is $32. Compared to some other brands (coughmorphecough) I can see that the brush has been carefully made, there is no sign of bristles out of shape or glue seeping from joins. The handle is matte black, which I really like, it adds a uniqueness to an otherwise 'standard' looking brush. Down to the important part; the performance of the brush. The bristles are so soft, I can buff, and stipple it across my face and it is super comfortable. It blends foundation beautifully and overall I was very impressed. My conclusion; I would definitely rate this on par with the Sigma F80, and I look forward to buying more brushes from XO Beauty.
