There's no baby diapers that will properly fit a 32 inch waist.
However for size 6 Luvs, size 7 Pampers Cruisers, Size 6 Pampers Baby Dry and size 7 Dollar General Gentle Steps diapers you can modify them to fit somewhat.
However if you want a proper fitting diaper you should go with adult diapers.
Dollar General Gentle Steps size 7 diapers will fit a 32 inch waist but only if you modify them.
That is to say that the Dollar General Gentle Steps diapers won't fit you right out of the pack nor will they fit properly.
However with some modification you can make the Dollar General Gentle Steps size 7 diapers fit somewhat.
Currently I'm wearing a Dollar General Gentle Steps size 7 diaper right now and although they don't fit properly they still are fun to wear.
They are very absorbent and very squishy when wet as well.
The way I make the Dollar General Gentle Steps size 7 diapers fit me somewhat is to peel off the cloth backing which makes them feel even better.
Next I take the Velcro Landing Strip and tear it in half and then take each piece and glue one piece of the landing strip to each side of the front of the diaper and extend them out.
Then the tabs will reach enough to secure the diaper.
However I still must use some clear packing tape to hold the diaper in place and prevent it from coming undone.
I do this with other diapers such as Pampers size 6, Luvs size 6, Pampers Cruisers size 7 etc.
Although I do wear mostly adult size diapers which feel even better I sometimes just enjoy modifying an actually toddler diaper and putting it on.
Even though the diaper does not fit perfectly they still are fun to wear.
If all you can get is some Dollar General Gentle Steps size 7 diapers than they are much better than having no diaper at all.
You just need to use a glue gun to glue the landing strip halves to each side of the diaper and then use some packing tape.
