Really? I said: The woman's blouse is big - blouse = shirt? no?
maybe Duo wants "blusa" as a translation for blouse.
Yes but in an earlier lesson camisa=shirt or blouse more consistency required
When do we use de verses da in this case. In this sentence, does it mean that it belongs to women in general compared to say if we sayed "a camisa de mulher e grande" which would mean a particular woman?
No, it comes from de + a, which has to become 'da'.
