Merry sweet castle JSK sizing (which style which sizing)

Hi, Im about to buy a Merry sweet castle JSK. But now im wondering which JSK was the S,M,L measurement JSK and which was only released in one size?

Was this the one , that was released in one size? If so what are the MAX measurements?
If not , where can I find the measurements of these sizes?
 

Im tried to look it up, and I only found out about the one size style jsk and the other was released in S/M/L sizes.
