My 30th High School Reunion is coming up in about three weeks and I have just discovered that my Kerr Modern tank which I wanted to wear that night has "grown" about three inches. I have used the search feature and read the various threads on how to shrink the waist. Most of the threads suggest moving "the apron edge buckle(s) and the under apron strap". My questions, then, are, where are the buckle(s) and strap that need to be moved, how much should they be moved to take the waist in by three inches, could I move all of the buckles (including the one near the botton hole) the same distance towards the back to attain the same result and on average how much would this alteration cost in terms of time and money?

Thank you for your advice.
