I prefer Geraldine out of the two of them, she does give advice now and then on what looks better on certain bodyshapes. Many women tend to get into ruts when it comes to shapes of clothes and what looks flattering on them and I think you do need more information when buying clothes off TV as long as it's informed!
I liked it when Pippa warned viewers that a jump suit being presented had a very short body so not suitable for everyone, we need more of that openess, especially with items like clothing and footwear which will simply be returned. Not everything suits everyone and it's silly to present items in such a way.
