I feel ashamed that I like cute things at my age

I’m 21 and I collect toys, dress in pastels, have tons of unicorn stuff, my hair is even dyed pink. but it’s so obvious everyone around me thinks it’s so weird and like I am acting like a child. which I can understand, but I don’t have any comfort elsewhere. I feel so embarrassed by it sometimes, I try not to dwell on it but I do really wish I was normal and interested in normal things for my age :/
