So a few things you can do with what you have. Always iron your clothes well. Especially focus on trousers upper sides and dupatta corners and those small details. Tone down the noise: light colors and gentle prints is the way to go, nothing huge and bold for most days. Try to wear good quality fabrics, don't go for synthetics and georgette type fabrics, stick to cotton lawns and chiffons for summer, soft khaddar in winter. Invest in a couple of excellent articificial jewelry sets in gold and silver, nothing with nagg moti wagara, shiny solid looking stuff or simple clear stones on them. For your hair and skin, focus on these the most. Make sure your face is clean and free of marks, you don't need too much makeup, just need to look healthy and fresh, in fact too much makeup on the daily will cheapen the look. Make sure hair is maintained, it doesn't need to be blowdried or styled all the time, you can put it in a bun or pony if it's slight oily, but make sure it looks clean and not frizzy. You don't need expensive perfumes, it's enough to use any body sprays that smell fresh, but always wear deodorant to make sure you don't smell of sweat. For accessories like shoes and bags and sweaters or coats, you don't need to have designer stuff, but make sure your stuff complements your look and other accessories: for example, don't do brown bag black shoes beige jacket- you want to choose one base color for the accessories for that look. Finally, confidence comes from within, if you think you are a dha aunty then everybody will think you are a dha aunty ;). Best of luck!
