Help with engagement outfit

Hello ladies I need your help putting together my engagement outfit for me and my daughters. Our theme for the family engagement is picnic like with a horse in the background. I was thinking we all do boots and thats how far I got lol. Please any help I will greatly appreciate. One of my daughter is 3 and my future step daughter is 13 if that helps thanks in advance.

Are you doing this for pictures or is this for an engagement party?

Boots would be cute! You can all wear dark color jeans, boots, and similar color tops?

boots, jeans, checkered long polo and cowboy hat...

how about someting like this for a more vintage look? I love the dress with the yellow and the boots. ruffles lace and cardigans

i TOTTALY agree with uhlease! love the boots idea think it would be super cute!

What about cute dresses? Everyone thinks jeans with boots but dresses look cute too and could be fun with the girls. You could coordinating patterns or colors and FI could have a shirt that ties them all in together.

thanks ladies for the ideas. they are all good ideas
