I guess I'm the only one with this opinion but I'd go for the Kelly and the PG. The Garden party doesn't sound like it would suit your needs right now. The Kelly is a dream bag that you will use and the PG is a special piece that offers a different look and use for your wardrobe.
I absolutely adore the jumping boots and have been tempted many times, what holds me back is the fact that I wear a Kelly or birkin almost everyday and I really hate the thought of my boot hardware matching my bag hardware. I'm aware that I may be in the minority here but I thought I'd mention it in case it's something that would bother you as well. If you have a lot of different bag styles in rotation then it's a non issue
Good luck deciding!
