Are these jeans/outfits work for me post partum?

I'm 4 months post partum, so it's time to give my elastic waist trousers a well-deservrd break and after a year, return to the jeans game. However, my body has changed a lot post C-section and I still have 5 kg excess weight from my pregnancy ( which feels a lot for my 160 cm height) and I'm breastfeeding. Are these pairs of jeans/outfits work for my current body? Also, how do you avoid that bulk of belly fat dominating when sitting in a high waist jeans?
