I'm short. When I was slim, some clothing did swamp me. It might technically fit but if there was too much fabric, the wrong cut or fuss it really would swallow me up.
I'm guessing the the OP means that there is a lot of fabric around the sleeves and the rouching at the waist might make everything a bit volumous.
I've no idea if that is the case with this dress though because I've never seen it.
