This is gonna sound stupid..but i need advice

I have a full time job. I work basically to pay my bills. Been there 3 years and only one raise. I only get by. I drive the crappiest car that ever was and its about to break down. Bumper is destroyed. Windshield is cracked all the way across. It sounds like a go cart. Its embarrassing to drive. My credit is horrible and I am trying to pay off a small loan to raise it.

But here's the thing. I want to dress pretty but I feel like I can't simply because my car is so awful. That sounds ridiculous right ? But it is true. I wear baggy shirts and leggings. Sometimes I want to wear pretty Fall clothes and boots but I feel like I would look ridiculous hopping out of this monstrosity of a vehicle.
