Reduce and keep bloating down for wedding dress measuring!

annasor70

I am getting measured for a wedding dress tomorrow and want my waist to be at it's best It's not terrible...about 27 " but I am wondering how to eat for the rest of today (dinner) to keep it/ make it smaller

So far today I have had a fruit shake with a little greens, ginger, apple, cherries, vegan protein powder, amla, flax and raw cacao powder.
For lunch I ate walnuts and an apple and one cup of vegan risotto (mushrooms, zucchini, tomatos).

I am not adding salt or eating anything salty. This is JUST for today!!!! I will be back to normal, healthy vegan eating after my measurements have been taken tomorrow.
Any advice on what to eat/ drink? Is alcohol bad?
