It's no one's business but yours and your husband's what you keep and what you don't. I don't hide anything from my husband either. It's not worth the hassle. If we can't be honest and trusting, what's the point?
However, I usually say I'm not asking, just informing you, that I purchased...so and so....he's pretty good about it, and I wouldn't ever buy anything large and/or expensive without running it by him to get his reaction. "Stuff" isn't worth arguing over.
Enjoy your little Susie. FW's are such fun!
