You need to wear clothes that reflect your stature - Вам необходимо носить одежду, которая подчёркивает ваш статус. (it seems to me 'stature' means social status here?)
Oops!

Yes, should've been status on second thought... a moment of indiscretion if you will I edited it now.

Thanks for the alteratives!

Although yea "stature", apart from height, also means "importance or reputation gained by ability or achievement"... but status is more natural in this sense

What is the context, Valda? Why do you use “need”?
Because someone (some fashion expert maybe) is telling off that person that he "needs" to wear clothing fitting to his status
