Mom keeps buying me 3XL clothes

Over the past year I've been steadily losing weight due to my job. From my of 250 peak, I've lost about 40 pounds. Now, I am super ready to fully focus on it and get to a healthy weight. One of the motivators for me has been clothes. I want to wear cute clothes that I could never wear before. I've been rearranging my closet and donating the clothes that don't fit me anymore (or just grown out of my style) The problem is my mom loves picking out random bits of clothes and sleepwear for me from Walmart. I know she does this out of love but she gets clothes that are 2XL/3XL. I've never been a 3XL! Even my old pants that were a size 18/20 have become unwearable without a belt. But recently, she bought me a sweatshirt that was an XL and said it might be too small for me. It kinda hurt ngl. Even though I'm not, I wonder if I still look that big. But I'm keeping my hopes up to get my goal weight! I'll keep going!
