Marta Smocked Midi Dress

Ordered this after loving the Fabian Midi I purchased but wishing for a green dress in a similar style. I was bummed to see this doesn't fit very similarly at all despite have the same smocked style bodies and puff sleeves. The smocking came way lower than expected and stopped just above my belly button creating a bump where there isn't one (For reference I'm 55, 170lbs, 34DDD, 30" waist, 46" hips). The skirt was also not as full as I thought it would be based on the photos. Lastly, I order a M (which fit me perfectly in the other dress) and it was a bit too tight on the sleeves and neckline. I worry if I size up, the long bodice would be even longer and looser. Overall no where near as flattering a fit as the other midi I got from this site. The hem also lands just below my knees which was surprising for a midi since I'm 5'5 and typically midi's end up too long on me. I would've preferred it slightly longer at mid-calf. The green color is what I wanted, but it doesn't fit me well enough to want to wear for the wedding I'm attending. The fabric also seems like it would be a hassle to steam out after my flight and looks a little casual or cheap.
