I usually buy a few here and there, I agree with the whole, are they comfy, are they the right size (they vary so much) and not to mention they are so expensive these days!

When I was about 8 months pregnant pg with DD I went to a sale, they had 3 packs for $2- bargin, I bought a heap, thought I would take the advise of some lovely BB ladies and buy lots of black undies so after I gave birth I could wear and throw out rather than wash them, well I tried them on and they are the comfiest undies ever... needless to say I washed them and they are still in perfect condition 11 months later .
Will be looking out for that sale again this year .
