Postlady needs advice

Here in the USA you can get padded briefs/boxers. REI has several options including this one http://www.rei.com/product/794386/no...-briefs-womens which does come in a size XL which is supposed to correspond to a 16/18.

You could also look at men's models which are nearly identical, but likely come in larger sizes.

Be aware padding alone may not solve the problem... it may possibly make it worse to add a bulky pad to an already bulky padded seat. You may simply want underwear that is totally seamless - like Under Armor seamless boy shorts (also come in a size 16) - though these seem a little thin.... (you do want something there to protect you from the seams in your uniform!) something more like Nike's tennis shorts might be better - unpadded, but seamless spandex exercise shorts.

One question - are the seatposts on the bikes quick release? Could you get a saddle that you like and mount it on a seatpost that should work on the provided bikes - the diameter of that is probably the same of most if not all of the bikes... then you could just swap the whole thing when you go to work and put it back when you are done.
