Reddit reviews Cheerleading Jacket Hooded Red Windbreaker (XS)

That jacket looks to be similar to this one. For the single black line on the front shoulder part, you could get some black fabric from a craft store and cut out the same design shape then sew it or use fabric glue/tape to apply it to the jacket.

This jacket is less expensive and would work too. If you want the black zipper line on this one, you could get some black acrylic paint and use a brush to paint this part as well.
