P&CO high waisted checkerboard pants

Brand new high waisted checkerboard pants UK brand P&Co! These pants are so nice but unfortunately this brand doesn’t take exchanges for the US yet so hoping to find a new home for them! They are a uk size 6 but I would compare it to a US 00 cause the waist is pretty small! The website says the waist is 30 cm! I am normally a us 0 but the hips and waist are to small for me so please let me know if you have any sizing questions hopefully I can help!
