Sizing

They have a sizing guide with detailed measurements.
However, the sizes do run quite small / asian sizes.

I recommend to order a size or two larger or take a look at the measurement carefully.
A little measure band in hand always is useful in shopping online! 

What i think about it
This cushion is really good for oily skin users like me. It stays matte until 4 hours and starts to become kind of dewy after. It also provides very good coverage to cover up my blemishes and redness. The cushion also has a smoothing effect to make your skin look photoshopped.

Is it worth buying?
You can either really love this cushion or hate it. I read a lot of reviews before buying it and was afraid that it's going to be a flop.

I personally really like this cushion because it's matte yet not too dry even for winter time. It works perfectly with primer underneath and occasional touch ups after the 4 hour mark :)
Powdering it with no sebum powders also help!
