BWT with a big butt and small waist...what pants are we wearing?

I've been going to the gym for a while and lifting while also trying to lose weight in my midsection. It's going well! But I need some new pants and I tried on like 6 pairs yesterday. Most of them fit my butt and my thighs beautifully but there was massive gapping at my waist. I'm realizing this problem is just going to get worse. I'm balling on a budget and still losing weight so less pricey options would be preferable. So help a fellow B out, what are we wearing??
