"This jumpsuit was utterly amazing, fitted well to size/measurements, was comfortable and arrived efficiently to New Zealand. I am beyond grateful for this jumpsuit and the beauty such holds and allowed me to feel x"
"It was a bit complicated/confusing to put on initially but once it's on it the open leg slit kept my legs cool. I loved how it also came with shoulder straps so that I can wear it with straps or strapless."
"Great jumpsuit. Looks so good. Billy j were so easy to deal with when I wanted to send back for a different size"
"So Flattering! I sized up because things tend to be too tight across my chest but it ended up being too big. I got so many compliments wearing this - a stunning piece. Billy J for the win EVERY time!!"
"Beautiful and great quality but didn't fit definetly runs on the smaller side."
"I love all your clothes. My fav at the moment"
"Love It. Fits great"
