Her sister in law seems out to sabotage her by dressing her so badly and cheaply. Chances are high she'd spend more money on herself to look stylish.
Charlotte and her styling skills came through and wonderfully!
I do hope Rebecca's family won't go weird when they see how pretty she truly is in herself and not just how she resembles her mum.
Brother and sister in law are definitely sabotaging her. No spoilers, just intuition on my part. Brother is probably sabotaging her inventions and sister in law sabotages her outfits. If her inventions are good and she fits in with high society, maybe the father would've made her head of the family, instead, since the brother has no talent in alchemy.
Okay even with her make over I am still in revolt with these color pallets. Also the ML's color pallet is driving me nuts too. Does the artist have a color wheel over there that can help them out?
