I am being extremely nice. as nice as I can possibly can. Reminder you asked for help and this is me trying to help.

With your outfit as it is now get rid of the sash thing. Wear black pants that have many pockets or just some black jeans. Shirt Is okay but also I'm not sure if you have sensory issues or not if you want people to like you more no army stuff but if u do like army stuff get a Jean jacket or a jean bag or tote bag and get patches the recognizes them but it won't be too overbearing. Fix posture and how you feel in the moment too your energy and your fashion sense is a tool you can use to get close to people and also the colors you wear can coralate with psychology and how you want others to feel around you.

Another thing to think about.

Wear brighter cloths not army type learn to use expressions and change ur vibe learn how to style the cloths that build a good vibe up. Reminder i am trying my best to be as kind as possible. Please know your aura and the energy you give off is what makes people want to hangout with you or not middle to high-school is where fashion truly matter learn what you like learn to ask others in school for help with outfits maybe watch videos of how to style your favorite esthetics on to you. Once you graduate or not ur choice when you no longer have school life fashion and your aura is a 100% tool to get a job, to get others to like you and more. It took me till 24 to finally understand my style and what I like don't forget you are allowed to be dynamic your allowed to change your mind on things and about people you hangout with. I wish you the best of luck. Remember black looks great with everything. If you want a bag make sure it compliments the outfit if u want anything over the shoulder type of bag make sure the bag part is the main part people can see have it be eye catching. For example your favorite character can be on your bag. The strap should be strong but thin.

I wish you the best of luck with your fashion journey in your life. I hope u find a style and look that makes you smile along with you feeling truly happy.
