Question about AP bustier style JSKs

I am looking to confirm the actual length of AP's bustier style JSKs, like their Chess Chocolate and Star Night Theater ones. They are listed as 89 cm and 90 cm each, but is this really their length? AP is just so notorious for having short dresses that I'm wary of the veracity of these numbers. I'd like to check before I go out and try to buy them. Also, if anyone is 5'8" or similar and has a picture wearing one of these bustier JSKs I would love to see where they hit above the knee! Thank you in advance~!
