I did waist train back in my skinny days... even now very overweight.. i have a much smaller waist than i "should" have for my size... naturally i was a 21 inch waist... i could get down to 18"... never could get past 17 & 3/4" ..... always passed out... which sux

it is hard... and it is worth it... but you need to be dedicated to it and suck up the pain in the beginning.
I love the look and i look at my old corsets and sigh... i know i will never get my waist that small again... Kids and extreme weight gain have ruined that unless i go the surgery route..
