How to get Vanessa just in bra

How do you do to take vannesas jacket and leave only the bra

 

it becomes an alternate outfit that you'll either unlock after getting to 1st dan or completing your first orb disc.

 

i dont think so, its costume A and my vanessa is 4th dan already

 

did you open up a new costume at 1st dan? How about filling up an orb disc. I was only stating what I thought I knew... but could be wrong though.

 

yep, sorry for my ignorance but I was wrong... oops.

 

i thought you meant the first orb which unlocks custome D, but apparently it was the first orb you buy, thanks for the help

 

My kanji reading abilities are limited, but it looks like it comes at a ranking or prize match (not sure which) around 5th dan(五段?).

Oh, and if you need to Fap, that is what the interweb is for.

 

Its an item called "no military shirt" for costume A. I'm not sure how I got it.
