I have previously bought the Helena white and black bras, i just needed a bigger back size... geting old, less active and putting on some weight!!! I have never tried the Illusion pants, but i am not that keen. Yes they fit (size 12) and are comfortable, but they have a very loose leg top. At the age of 72, i tend to wear slimline panti liners, just in case i sneeze, etc. :-) These Illusion pants cannot keep liners in place, so need to look at other options that go well with the Bras. However, they must be waist height, with elasticated/fitted legs. Any suggestions gratefully appreciated. Very Kind Regards, Carol.
