I need research into clothing (denim jeans)

i am writing a project on denim jeans that looks at what type of wearer / customer /user benefits most from wearing denim jeans

I need research that looks briefly into 3 sections

1) which sections / parts of the population need/benefit most from 'good fitting jeans' ? So is there a section of the population that has particular benefit ? do they need clothes / jeans to fit as they have a medical / mental condition that meand good fit is must / benefit. Is there a low income part of the populat ion where good fit equals long life of clothing and therefore high long term value and affordability.

Would people coping with menopause benefit from perfect fitting jeans that adjust to their shape. Would 'overweight' people benefit from good fitting jeans. Are good fitting clothes important for mental health ?

in summary: a list of groups / segments of the population that would benefit from good fitting jeans.

2) Are there any Government initiatives/ policies that the manufacture / design of jeans can take advantage of or that they can be related too ?

eg they are being designed in the North of England so they can be associated with the 'Governments leveling up' initiatives . But are there any other Government manufacturing/clothing/ research initiaties that are relevant etc ?

In summary
Long descriptions but simple research needed

I dont need large reports, just the details/facts/numbers and the source/reference for each fact

Please let me know your cost and what you will do and deliver in line with the fact i dont need a huge report !! Just the facts
