My main suggestion for Juliana is to look for cozy (not oversized!!) knits, dress pants (or dark denim trousers), and simple closed toe pumps or booties. Because she's looking to stretch her budget, I also chose some pieces that are great layered with a jacket for winter but will easily transition to spring with a skirt or cropped slim ankle length pants.
This would be a great outfit for a casual Friday as the dark denim trousers still keep it professional but it's a bit dressed down compared to the other looks. If Juliana feels this outfit may be too casual when compared with her husband's suits and ties - she could easily throw on some khaki colored dress pants to make it feel a little more dressed up.
