3Sixteen CS 100x Fit Check and recommendation

Bought these 3Sixteen CS 100x in Feb 2024 from Rivet & Hide and I don’t if it was my post baby weight at the time or whatnot but these feel too baggy now both in the waist and legs. I have strong thighs and calves as a muscular cyclist with a short/stocky-ish build at 5.7” and 163 lbs.

Those jeans are a size 33” but measure closer to a 34”.

When I use them with a belt the fabric bunches up too much and makes them painful to wear in the waist. Debating sizing down 1-2 sizes in the CS100x or also looking at Iron Heart’s 888s (I think 634’s hem is too wide, aiming for 8” but on some pictures they seem better than others) but would welcome any thoughts. Added a pictures of my now too small and ill fitting PBJ XX 013 to show what we’re working with.
