OK... Something else very strange just happened. I could've sworn that my underbust couldn't possibly get any tinier, yet I just measured again because my 32 band bras weren't digging in any longer... They're actually getting really quite comfy and at first I suspected I needed new bras... And I probably do cuz the underwires are starting to dig in... Which tells me it's time to go up a cup... But the loss of elasticity I thought was happening? Apparently not.

It's VERY VERY strange but I seem to have lost some more underbust. It's now literally like 31.5" or 80 cm.

My shoulders are still just as big though so I actually need to go up a cup size and down a band size on my end goal size. 32DD! Yikes!
