Interview outfit HELP! (for girls)

Hi! My interview is coming up and I am planning on getting my interview outfit soon.
I was planning on getting dark color skirt, pastel tone blouse and dark blazer, but do youguys think it's okay to go without a blazer? Vegas is going to be super hot. I wonder if girls wear dress without jacket to their interview. What are youguys planning on wearing it? or what did you wear to your interview?Any advice would be appreciated!!! Thank you so much!!
