Hello :) Finding something to wear everyday to Uni can be difficult. You need to find something that is easy to throw on every morning and style easily, those would be the basics. Find a jumper or jacket that make you feel confident and get more from it in different colors so you don't get bored. For your Hijab, we recommend getting neutral veils, with minimal patterns that can easily fit most of your outfits without having to worry if it's going to match or not. If you get bored from the outfits being to basic or repetitive, accessories can be really flattering and can easily change an outfit. A belt, a clunky necklace or even a colorful scarf.
We have an article dedicated to college hijab fashion, you can take some inspiration from it here.
You can also check out Hijab Fashion Section to help you find different way to style your Hijab.
As for Petite wear we recently wrote about stores that carry petite lines, this can help you as well.
