This pocket detail is one of the major reasons I chose to knit Shellseeker. The split hem is another.
If I zoom in on the sweater both of these details look pretty, but one of them has a dirty little secret.
This was taken yesterday:
This is what happened overnight:
Even the modified collar is starting to misbehave as well…
I already tore it out the offending hem once and re-knit it loosely. Do I need to go up yet another needle size to fix this?
I am at a loss. While I await your sage advice, I’m going to work on the first sleeve.
Knit Me For a Loop 
Going up a needle size should help. I’ve seen some knitters do a row of seed stitch between stockinette and ribbing. I personally don’t like that look, I’ve tried it a couple times. It did work though.
Last sweater I had this issue on, I ran a 1 mm strand of elastic through the bind off. It worked like a charm and let me avoid ripping & re-knitting. I typically make the lazy knitters choice 🙂

I appreciate the advice and will save that knowledge for future reference. For whatever reason, a simple blocking did the job. 🙂
