Feeling like an imposter around other girls - need some sisterly advice

As-salamu alaykum, sisters. I feel a bit out of place around other girls who seem effortlessly put together, smell nice, have lots of friends, and are just naturally social. I often end up feeling awkward, silly, and like I don't belong. I'm trying not to blame it on my hijab (alhamdulillah I still love wearing it), but sometimes it makes me feel frumpy. I cover my neck so I don't get that sleek Vela-style drape a lot of the girls at uni have. I also don't wear jewellery or perfume (just unscented deodorant), don't wear makeup, and I have to wear glasses because my eyesight is very bad and contacts aren't an option. Most days I feel clumsy and plain unless I'm at home and can be more relaxed. I do like most of my clothes but still feel awkward in them. I'm self-conscious about my body, the areas I can't easily change, my curls getting flattened or frizzy under my undercap, still dealing with acne, and crooked teeth. It feels like I have a decent base but can't reach my best look because of Islamic choices and budget limits. Sisters who seem effortlessly confident - any tips? Small practical things for modest styling, hair care under an undercap, skincare on a budget, or confidence boosters that worked for you would mean a lot. JazākAllāh khayr.
