Former Tudor reenactor to the rescue here!
An authentic Tudor technique is to make large-ish (say, 2-3" across) flat "top pleats" where two pleats bump up against each other rather than, say, lapping around all in the same direction. These top pleats have more pleats beneath these.
When held up by a bum roll they fall pleasingly, and are the perfect way to take up all that "extra" yardage (for a Tudor skirt, what you've desribed is not extra! So step away from the seam ripper, citizen).
I can't find a good link for you, but google image search "tudor tailor", and enjoy the garb porn!
Bum roll: a neck cushion might work (depending on the wearer's waistline! But easier almost is a thinner version of a bolster or any tube stuffed with some hollow-fibre - even a relatively hearty tights leg would do). NB - the bum roll doesn't sit around the waist, but more like around the hips.
Other relatively easy things to do (you mention you're not a slouch with the sewing machine) - any one is nice, all is fabulous:
If you can also, find hoops, or perhaps skirt stiffener or padding sewn into the hem of the skirt. Heck, if you live close to SarfEssex I'll loan you my farthingale.
Square low(ish) neckline might be easy to achieve - depending on level of authenticity required, could even be as simple as taking a long- or 3/4 sleeved t-shirt with a scoop neckline and pulling the front corners to closer to the armpits, fasten with a couple of brooches or earrings to either a ribbon drawn round the back, or DD's bra (if she's of that age). Consider a bustier or corset as a base (let it do all the foundation work) and just tack some things onto it.
The simplest French hood (think Anne Boleyn's hat) can be made with an Alice band and some cardboard. A bit of opaque fabric hanging down from the back. There's online patterns for this, too.
Pearls and jewels on any surface that doesn't run away fast enough. Big pearl necklace that wraps around the neck, then dips down into the corners of the neckline.
Finally, skinny sleeves, with very large cuffs, preferably in [faux]fur, and fake undersleeves (the big round ones you see Tudor ladies wear).
Don't know DD's age, so re-calculate anything you need to to more age-appropriate supplies, as appl.
PM me if I haven't made your eyes glaze over already...
Best of luck!
