Apt 9 Purple Long Dress with a One Button Purple Sweater

This is a apt nine beautiful purple dress with a purple almost new sweater. I worn it twice with one button in the front of the sweater. Is it extra large it’s always a dress sweater arm to arm 22. The length is 49 inches it does have slits up both sides. The lavender dress is 23 arm to arm and very very soft. Nothing wrong with either one of my favorite dresses.
