Realistic goal in inches?

LexieeLovee

Okay I have a serious question....


So, recently I've decided to start tracking my inches instead of my weight in lbs... I bought concert tickets yesterday that I'm SO EXCITED FOR .. And I wanna have a goal weight for the event ... I have 
3 months until the event..

I'm currently:
Waist: 36 3/4
Belly button: 40
Arm: 11 3/4

What's realistic goal for me in inches?
