I bought this outfit to wear to one event for my husband's cousin's wedding. I really liked this outfit and my in laws were very impressed with the quality since it came from Amazon. I ordered the 4x and 5x and the 5x fit, but was still a little snug across the bust and a little on the upper arms. It might have been ok if I had opened up the extra stitching. But I'm currently breastfeeding and have a 10 month old and was afraid I would rip the sleeves trying to pick him up or that he would spit up or spill on me and ruin the fabric. Ultimately I decided that the neck and sleeves fit a little too snuggly for me to be comfortable even if I expanded the bust. I was very impressed that the hip was wide enough on even the 4x and it was very flattering. I have roughly a 48 inch bust and my hips are around 50.
