Best Jeans for Thick Thighs & Big Bottom?

[ColourChanger]

I've got thick thighs and a big bottom, I'm a size 18 and finding it hard to get straight fit jeans that support and shape my bum without making my legs look like sausages. I'm short so boot cut or anything wider at the bottom make me look stumpy.

Any recommendations?

The Sienna from Mango is very flattering

With apologies for the awful name - the Mom fit from M&S

Second the M&S mom Jean. I have a large bum in proportion to the rest of my body and they fit so nicely. I managed to fit into them a couple
of months after giving birth and they fit comfortably and look nice even though I’m still chunkier than before. I am 5”7’ but they do shorter leg too. Regular is probably 7/8 on me.
