What is the ruling on paying an additional fee for cash-on-delivery service for purchases displayed by immodestly dressed female models?

There is no harm in paying an additional amount for home delivery service because it combines a sale and a known wage, and this does not affect the validity of the contract. Likewise, there is no harm in buying clothes to adorn oneself for the husband and wearing them according to Sharia guidelines, which include not displaying oneself immodestly with them as long as they are not covering adequately.
