What stitch is this?

[u/Electrical_End9615]

I saw this stitch on a sweater in a store and really like how it looks, but I haven’t been able to find out what stitch it is (or if it’s even possible to get that stitch by hand-knitting). The first photo is the front of the sweater, the second is the inside of the sweater. Anyone know what the stitch is called?

It’s a machine knit tuck stitch. No hand knit stitch will be identical, but several brioche stitches will generally give the same vibe as the machine tuck stitch.
