Need a very quick diet

I'm getting married in 3 weeks 😱 I've obsessed over this dress and have gotten it beautifully tailored and spent the $ for all of it.

Recently stopped BC and lost weight in the wrong areas and gained an abd pooch = it bunches up above my hips.

Not to be too vain, but I've chosen this dress BECAUSE it's form fitting. I need to loose about 8-10 lbs to make this look right. Tips... help?!

I realize it's not necessarily gonna be a permanent wt loss. I just need this dress to fit as i intended. Thanks ladies 🤠😎
