Is this suit appropriate for an interview? If so, any tips on wearing it?

I have an interview scheduled for Thursday, so I went suit shopping as I didn't have one. I really loved this tan suit, and it was on sale for 67% off, so I bought it. The more I think about it the more I'm worried that the tan and pink is not professional enough for an interview.

Would this suit be okay, or should I try and return it in favor of a more traditional suit? If it's okay, should I go buy a pocket square, or new shoes? Any other tips, or problems? If you think I have time I can even get it tailored, if it's helpful. Thank you guys so much for your advice!

Whoops, I forgot to post a pic of the suit, sorry.
