Making my life difficult

Okay, so this could be my fault for not asking him about Halloween earlier. I was counting on him wanting to be Buzz Lightyear. Premade, free costume that we could borrow. It would be easy and I wouldn't have to worry about making anything since I am getting to be quite pregnant and this is a really busy time for me and selling mermaid costumes.

Anyway, wanting to make sure he would enjoy Halloween and would actually get dressed up, I decided to give him a couple of choices of costumes I could easily make, along with Buzz Lightyear. Monkey, frog, or Buzz were his options.

What did he choose?

Frog.

What does this mean for me?
I either have to find a pre-made frog costume for $10 or less (I'm a cheapy and really don't want to spend more than $10 0n a costume) or I will be making him one.

I could make him one from hoodie sweater and pants... which could be $15-$20. Possibly less if I use green pants we have (which have stripes down the side and possibly wouldn't match the hoodie). I do worry about it being hot and the sweats being way to warm though.
It's an easy/fast make... I just have to hunt down a green hooded sweatshirt or jacket. (ironically, I think I had one that I took back in favor of one I liked better. Yes... I'm almost positive I had one and I remember thinking when I bought it, OH! I can use this for a frog costume if he wants to be a frog next year. Of course, 2 months later I didn't remember than when returning it).

I could spend $10-15 on a knitted frog hat (from etsy) and then pair it with the green shirt and pants I have.

I could get a costume off of ebay (hopefully for under $10 after shipping... good luck)

Or I could drape his hooded frog towel around him and pin/velcro it and call it good.
Here is Jon modeling it :)

SOOO....
If you were a 36 week pregnant woman, with your husband to be out of town from the 19th-25th, and you were "working" on the side, what option would you go with?
