My question is can I still pay zakah to her to meet her personal needs and expenses, which she would use to buy clothing, and other miscellaneous expenditure?
بسم الله الرحمن الرحيم
If her deposit in the bank does not reach up to nisab i.e. she is eligible to receive zakah then you may give her zakah money. You should make the intention of zakah while giving to her. Do not tell her that it is zakah money.
Allah knows Best!
