Slapping on a lot of brand does not equal a good coord. This is honestly horrid in all ways. The bag doesn't fit the coord at all and the pose is super unflattering, especially since the blouse is already tight enough. The gloves are the matching set but in this coord honestly it looks pretty cheap. She'd be better off with lace gloves/wrist cuffs that aren't fingerless and also a long princess sleeve blouse to take the attention off her upper arm and make her seem more slim. She also needs way more poof rip.
I think the shoes are also just straight from the matching set, but they don't suit her and make her calfs seem a lot bigger because of the tiny heel. It also looks like she kinda shoe horned that darker pink in.
She really shouldn't have used her actual hair and just got one of those Marie Antoinette inspired wigs with the curls and stuff, preferably in a blonde color.
I think this coord has potential, but it's pretty sad to know that this isn't her first time wearing the dress for a big event.
