Should I keep my cosplay or save up to buy a new one?

Around last year I bought a NSO cosplay off microcostumes but

Pros: I heard that microstumes is a really good brand and the quality is better than doki doki

Cons: there is this really weird and noticeable going from the front of the neck to the chest and one of the rings holding the suspender skirt fell off and the white shoulder ruffles are MASSIVE

Should I keep it or should I buy a new one from Doki Doki Cosplay?
