I went to the wiki to try figure it out the best stats deco for the girls(including the 3 from the event) and this is what i figured it out.

to make it simple, i'm using for the stats S(small), M(medium), L(large). The order is feet/boob/height

LLL 4

SMS 3

MMM 2

SSS 2

MLM 2

SSM 2

MSM 2

LLM 1

SLM 1

LML 1

MLS 1

MLL 1

SLS 1

As you can see the LLL is the best followed by the SMS. Hopefully the new girl is going to make it more balanced.

If i did something wrong feel free to correct me.

ps. This is what happens when is late and i'm bored lol
