AITA I argued over a dress my mom gave it to a relative

I am 19F. I got a dress from a friend as a birthday gift , it is a sexy long bodycon dress with a huge cleavage window. I always wanted a sexy bodycon dress and my mom never let me get one of those. I told my friend and he bought me a dress whatever I picked at the store and it was really expensive as well. My cousin recently got married and they were supposed to move nearby to a rented place as they delayed moving in, the landlord gave the flat to someone else and now they are staying with us for some time till they find an another flat to stay in. She didn't have a night dress and my mom without my permission just let her choose whatever she wanted from my wardrobe to wear to sleep. She ruined the dress completely. It was my favourite dress. Not just the dress, later when I asked for my expensive makeup I realised mom has let her use it , and she idk how she has used it but she has completely changed the shape and the makeup has slipped out and all the outer packaging has makeup on it, it looks disgusting to touch. My mom said she let her use it, she'll pay for the stuff but when I told her the price she was baffled she tried to return it , I said it is ruined and I can never use it again. So she only gave me 30% of the total and said sorry. I told her no, I want the full price , don't want the half ass apology. She got angry at me and stopped listening to me and ignored me while I talked. I pushed her multiple time, asking for it again and again and she got angry at me saying she has already said sorry so I shouldn't push for it anymore. AITA for asking for the full money of what she gave away to the new bride without my permission. Is sorry enough? I don't earn that much, I sometimes do freenlance but I don't have enough time to earn enough , I have no way of buying those things back rn, I'll have to save for months to be able to buy all that back. The dress can't be bought as it was gifted and meant a lot to me because of the person who gifted me.
