A second email for a change of subject, which is aimed at Rebekah and her tutors.
By talking about an 'over 65' market you have assumed a market that is amorphous, even though it covers an age range of up to 40 years. Your tutors have failed to realise that, as with any other product, such a huge market sector needs to be segmented.
I would suggest that the over 65s can be divided into at least 4 segments (other posters may suggest more).
These are
1) PASTEL PEOPLE: More likely to be over 80, they are the more conservative dressers and have a liking for paler colours and skirts. There is a double page M&S advert in the sunday papers, three sweaters are featured, all are in a pastel colour, one has embellished shiny flowers on the front, one is cowl necked and one has a boat neck. M&S has this market more or less sewn up.
2)COUGARS: Older women, who always vamped and continue to do so, very slim, high maintenance with a liking for animal prints, décolletage and gold bling. Not comfortable with admitting that they are getting on a bit.
3) COMFORTABLE DRESSERS: Live in track suit bottoms, leggings, T shirts and fleeces. Probably would be hard pressed to find a skirt in their wardrobe.
4)AGELESS DRESSERS: probably the majority. They wear the same clothes women aged 30 - 65 wear. Can, and probably do, swap clothes with their daughters.
Obviously each segment can be sub-segmented and others may suggest a major segment I have missed. You need to identify which segment will be most likely to shop in the location (sub brand within a store) given to you and focus on their specific needs.
