How do you single moms afford to look nice 24/7?

I’m a single mother. 27 and I’m tired of looking like a slob 😂. I wish I could do my makeup and afford new wardrobe. I see other single moms with energy, hair done, nails done, nice clothes always looking new. Is there any cheap clothing sites to atleast look decent? I’m tired of looking like a bum. Sorry if my posts doesn’t make sense.
