Spring outside photos for family

Hi all! I just signed up our little family for outside garden photos in the beginning of April. Hubby and baby girl have outfits ready - mama on the other hand needs help.

I generally wear a size 14, curvy. I have hips that are huge and a big ole booty that puts Kim Kardashian to shame. 🤦🏻‍♀️ But am fairly flat chested.

Many clothes recommended? Need something spring time that doesn’t cost an extreme fortune. Bonus if it’s decent enough for a church baptism for my niece.
