sorry, my mistake, i went to do a bit of research and it seems the mod got a unoficial update, i tested myself and she has now a second outfit and some major changes i didn't got the time to test you need two things if you're using the version 2.4 of AiO mods this is the version i use so how i tested. i think, can't be sure that if is a older version you will need just to follow step 2.
step one:
Mega
downloit it, you may have google say that is not safe, but is just a java script for replace, you must go into (Hazumi and the Pregnation\PPLSS\www\mods\MOD_Nami_v0.1) and replace your file there, if you wanna do yourself the guy which i got this from at preg-chan said you could:
"just go to ur Nami.js, open with notepad
Ctrl+F search for <indents>
starting from that line, look down and find all the indents, change the number to 3 or 4 according to that picture posted "
i choose to download the file and it worked for me
step 2:
Mega
download it, change the name to just "Nami" and go at (Hazumi and the Pregnation\PPLSS\www\img\pictures) and replace the folder there this will give new clothes to nami and maybe some more things, i not fully tested, just the install part.
but the dev said :
"I'm sorry to have kept you waiting for a long time.
Finally, the correction and addition of the standing picture is completed.
I will post a link, so please add it yourself. "
if your version if 2.4 like mine all should work smooth, if is not and you got any problem, you know where to find me, hope this time it works for you.
