Now to be honest I went down a size just because I’m on a weight loss journey and it was the last size that I could fit. I love mostly all the snatched associated items that fashionova carries, I’ve bought plenty of them prior to the purchase. Like I expected it was snug as a bug in a rug and fit me oh so right. I’m 5ft 130 so I feel like depending on how snug you want to be will determine whichever size you should get. The jumper bunches at my ankle so I assuming it’s tall girl friendly.
