Throwing your own baby shower

Katy • Married to my best friend! Trying for Baby 2!
My husband and I didn't have a wedding or reception. We just went to the courthouse. I've never had a big birthday party or anything either. I know my sister will throw me a shower. She through our sister in law one and it was very thrown together. This is our first healthy pregnancy and I want to celebrate it. Do you think it's tacky to throw my own shower so I can get the shower of my dreams?
