You’re probably not doing anything wrong; it’s most likely just that your body takes a little longer, which is 100% normal.
If you have more muscle on your torso, it may take a little longer.
It’s easier & faster to mold fat than it is muscle.
So be patient with yourself.
Some other things to consider are: corsets don’t HAVE to be closed in order to waist train or get a waist reduction.
Many people wear corsets with a 1-3 inch gap in the back and continue to see results.
If you have a rib and/or hip spring that is a bit too small, your corset may be tough to close.
Why?
Because at that point your at ribs & hip bones.
If you want to bone train, that’ll take a while.
If you’re like me, and want your corset CLOSED, here’s my tip: slow daily tightening & loosening.
For example, say you have 2 more inches in the back until your corset is closed.
Well, then every day you’ll tighten up your corset a teeny tiny bit.
Say it’s 2pm, tighten up corset, leave it like that until 3pm, and then loosen it back up until 4pm.
Then tighten it back up to the same tightness until 5pm, loosen it until 6pm, and so on & so forth.
This always works for me.
Do this for a week or so, and I’m sure you’ll finally have your corset closed, or on it’s way to closing!
