My friend did not say 'thank you' for some gifts I got her! Should I still be her friend?

So I was really excited to give my friend some great quality clothes that were supposed to be sold on my online shop! But I had too much stock and I needed to give some things away! I gave her about 3 huge bags of clothes, lots of them brand-new. I can't even remember if she said thank you, but she seemed very happy. I left her house so that she could see the clothes. I was expecting her to text me saying thank you & that she liked the clothes.I got nothing. For nearly 2 weeks she never mentioned anything. I saw her oneday & asked her why I never heard from her & why she didn't say thank you. All I got was that she was going to text me, but her battery died & complained that some of the clothes were too small!!! I was thinking, how dare she even moan about the clothes not fitting her. We are about the same size & if she doesn't fit them thats her own problem!! She said that as if it were MY fault!! I was so shocked and a little hurt! I was never raised to complain if a gift wasn't too my liking! It's rude & plain mean. I totally regret giving her the clothes. I could've made good money out of them. Another friend was really unappreciative when I gave her a Gucci belt from my holiday, shoes & makeup for her birthday. She never even got me anything for my birthday!!. She didn't really say thank you or even look happy. These are meant to be my best Mates. I feel like ditching them and finding new friends, because I can't go on like this! What should I do? Are they true friends?
