Blue Lilly is coming!

I can't tell you how excited I am to have Wendy from Blue Lilly coming to photograph my family next month. Ive admired her work for a long time and somehow feel this kindred bond with her- I know I'm freaky- But I love her style. So I contacted her a couple months ago begging her to come to Calgary and a couple months later she announced she would!
YAY do the happy dance of joy! No really I basically jumped up and down.
I love that she adores color as much as I do. But I have to admit I need some help my friends. I know it shouldn't be this huge of a deal- I should take into account the lesson they had on modern family about family photos being so perfect and then the all dressed in white family gets in a mud fight- I really know I should be laid back and not care so much...
But I really want these photos to look good. My kids are at an age that I really want to remember them in. And I think it will help me be motivated to exercise better. And stay on my bikini bootcamp diet. Family photos will do that to you- great motivation. In a perfect world Id have these amazing kids with- no whining- temper tantrums ect- well.....we'll see what happens. Harrison is quite my tantrum boy right now. It scares me. just a tad
Anyways even though I shouldn't care that much...I'll be honest I do... and I need some advice... I have me and co cos outfits figured out. Im wearing an aqua dress with a crazy necklace co co is going to be in a rainbow stripe colored dress... BUT HOW DO I DRESS THE BOYS?
I have to be honest and say that I really dont know how to dress boys yet besides the polo shirt and khaki shorts- because thats basically what Brandon wears. And I grew up in a family of all girls.
So do I layer? Put something underneath a polo- a jacket? I really like this pink one Harrison has on- but is that mean putting him in pink? Like will he say MOM WHAT THE HECK DID YOU DRESS ME IN? IN 10 years from nowI don't know I just like that pink looks so good on him! I need an outside opinion- cause I totally think like a girl.
What about pants do I put them in Dark Jeans or is that too casual to go with dresses. Do I make the boys match or go with completly different outfits. Im thinking different- but should they be the same type- and What does Brandon wear? Uggh Im not good at guy fashion sense.
So help me out-please...
If you were having family pictures and wanted them really bright and eclectic and modern and whimsical- what would you dress your boys in? Any links to cute outfits would help me so much!
Love, the boy fashion illiterate girl
