mercedes felt her cheeks burn blank her outfit was all wrong.
options: because, although, unless

Explanation:

To combine the two ideas, we need a conjunction that shows the cause - effect relationship. Mercedes felt her cheeks burn because her outfit was all wrong. "Because" is used to introduce the reason for an action or feeling. "Although" is used for contrast and "unless" is used for a conditional situation, so "because" is the correct choice.

Answer:

because
