Free People Pink Ombré Halter Silk Dress

I have worn this dress to two wedding and have never received so many compliments. It is a halter neck with two buttons for closure and dips low into the back and has a tie. It was originally a size small or size 2/4, but I altered it to fit more an xs or 0/2. The dress is still a little big on me and would easily still fit a size small. I just took up the neck a little bit, because the torso on it was so long. I am 5’2”, which is why the dress looks full length, but would maybe hit at the shins of someone taller. It has a slit up the left side of the leg.
