There is a fashion cliche which states - If you were old enough to wear it the first time, don't wear it when it comes around again.
I think this is true of Aviva. While the clothes might actually be bought in the year she is wearing them, they are not particularly flattering to a woman in her forties. The old marm fashion look is best worn by young things where it is a contrast versus being worn by someone who looks like they just dragged it out of storage from the time they last wore it.
There is a way to dress well for one's age without looking matronly or being a slave to fashion. I think Lulu for the most part always looks great - not dressed as mutton disguised as lamb nor does she look matronly.
I think Ramona also dresses poorly - she needs to rethink all of those unforgiving tight satin mini-dresses which look like they were picked up at a store catering to prom queens or disco impersonators.
