I will try and help with a few pieces, though I am not an accessory guru and I don't want to set you wrong and cause confusion
Trucker/4speed's hat $12 ish?
Princess Pristina's wand $10 maybe. If you decide to sell I need this one
Lavender jump stand from Rosette's Prize Day - Pass
Sweet Clover's picnic basket -pass again
Princess Amethyst/Sparkle's hat with ribbons (they are a bit crinkly) -8-10 I reckon
Baby Berrytown's flower comb - hmm im gonna pass on this
Baby Noddins' brush (not pictured) $2?
I forget whose they are, but the blue car comb (Chief?) and Grasshopper comb. Boys combs I've always seen for $8-10
One of the Candy Cane clips. I think it might be Caramel Crunch but I can't totally remember. Mine were $6 but not sure that's accurate
Display card from the Snuzzle release of the Grooming Parlour featuring Sunburst and Gusty's names -pass
Megan's UK outfit (some wear to this)
Aqua DnW baby bottle. -mine was $5 but again, get a second opinion
Yellow brush belongs to one of the BnGs and I am not quite sure why it is in this picture... $6 I would think
