I need halloween help!

As one of my favorite times of year approaches I am freaking out! Usually I have family themed costumes planned and bought by August or September at the latest. This is the first year I have not been able to talk Weston down from wanting to be something weird. So Wes is going to be Diego from Go Diego Go. Due to the fact that he is a white boy and the costume isn't all that involved I think most people will not know what he is. Westom wanted Jamers to be Dora but that is obviously not happening. Jamers is going to be a boxer ( i think ). What I really need help with is figuring out costumes for Tay and me. We don't mind purchasing costumes but with my prego belly this year is for sure challenging. All the pregnant costumes online are lame and I don't think I am really big enough to warrant a maternity costume. Please give me some costume ideas for m and Tay this year and help me save our Halloween! I know this may seem dramatic but dressing up for all of our halloween festivites is truly one of the things I look foreward to all year. PS -- I expect some awesome thoughts from the most devoted halloween celebrator I have ever met- Mrs. Nikki Tolman- seriously you should see her house for Halloween! I believe last year she even made homemade butterbeer for all the neighbors! She is truly an inspiration.
