Tucked buttoned shirts become 'untucked' when adding too many layer details

Yes, this is a known issue that happens with too many skin details.

Thanks for your reply ! It's nice to know why this is happening.
Do you know if this issue is planned to be corrected ?

I don't work for EA so unfortunately I don't have that kind of info. Since there aren't that many me toos on the original AHQ thread (linked in your post), I would post there as well and make sure to me too.

I have the same problem and it’s very annoying. 

Had this issue with a Sim who had body hair, tattoos, skin details and scars. After becoming a Werewolf, I decided to add one more scar, but it was one too many — not only his buttoned shirts got untucked, but I think some other Sims’ as well! (Or maybe it was a recency bias on my part?)

After removing one skin detail the issue disappeared on my Werewolf. 

Given the new tattoo system in Hobbies & Businesses seems to use more layering, this issue could become really prevalent in the coming weeks. 

Same here! The shirt seemed to tuck back after I removed a wrist accessory.

Hi Eggbeatersims 

moved this over to the layer issue.

Please make sure to upvote this.

Also having this issue with certain skirts. If I remove all jewellery accessories (earrings, necklace), the tucking reverts to what it should be. If I just change the earrings/unseen necklace nothing happens, they need to be removed first. Removing lower accessories did nothing.

Untucked bug. Only 2 visible skirt buttons. (Accessories CCSP, top/shoes LD, skirt CoL, gloves MWS)

Once head accessories removed, top tucks correctly (4 buttons visible)

Mac, mods removed (fresh save). Sim placed from the gallery.
