Review by Zaynab on Aug 26, 21 review stating Order up at least 4” bigger in dimensions I am a dress size 10 and my waist is 29”. I’m 5’2” and I weigh 132lbs. I bought this in a 1x and I fits (almost) great. When I button it all the way there is little windows between each button though the material does allow me to adjust it is definitely snug. I’m going to get it in a 2x which I think will be perfect. Keep in mind, with my measurements, I can usually fit in most standard things but with bodysuits it’s a hit or miss. A few other ones I got in a 1x are super baggy on me but this one is not. I only wear it on my non-bloated days lol. I would assume a 3x would technically be a size 13 dress since a 1x was a size 10. That measurement table is the same for all the clothing even though they are vastly different. Last thing, Yandy does tend to make their sleeves super tight so if your a bit juicy in the handles keep that in mind. I’ve had to return stuff many times because of that (also, I like to life weights) since I love having sleeves. I hope this helps y’all out there! Much love 💕
