What size shaping bodysuit should I get if I weigh 180 lbs?
At around 180 pounds you want the L/XL in this seamless zip up bodysuit, not the XL/2XL. Size up only if your bust or hips are at the top of the range, because going a size bigger for comfort is what kills the compression you bought it for.

Sizing on this one is doubled, so you are picking between S/M, L/XL and XL/2XL rather than a single letter. At 180 the hips and the bust are usually what decide it, not the waist, because the waist is the part the garment is built to pull in anyway.

Video transcript
If you're 180 pounds you're most likely gonna be a size L/XL in this seamless shaper bodysuit. The clasps on the inside are what actually suck your body in, but this zipper is what makes it completely invisible under all of your tops, all of your dresses. I have never seen a bodysuit go so viral because it literally makes your waist disappear. It is nobody's business. And if you have to use the bathroom, don't worry, because it does come with a little hole down here for you. Thank God, because I cannot stand wearing a bodysuit out and then I literally have to be like butt naked in the Walmart bathroom stall. I genuinely did not expect to love this bodysuit as much as I do. And with the built in bra to fit all cup sizes, I genuinely understand why this bodysuit has been sold out so many times. SHAPERX just launched so many new fall colors, so I'm gonna leave this link right down below. Just make sure to grab your color and size while it's still in stock.
Why L/XL and not XL/2XL?
Because the compression is the whole point. If you size up to get more room through the hips you lose the hold through the middle, and then you are wearing a slightly tight bodysuit instead of shapewear. The fabric on this one has real stretch in it, so L/XL will go on at 180 and still do its job. XL/2XL is the right call if you are above that range or if the leg openings on the L/XL genuinely dig in when you sit down, not just when you first pull it on.

What if I am between two sizes?
Measure three things before you order, not one. Waist, hips and bust. Most sizing mistakes on a zip up bodysuit happen at the bust, because people size for their stomach and then cannot close the zipper over their chest. If your bust is the biggest of the three numbers, size for the bust. You can always get more hold through the middle with the inner hooks, you cannot make a zipper close over a cup size it was not cut for.
Does the built in bra work if you have a bigger cup?
Yes, and this is the part I was most surprised by. I am a 36DD and the built in bra actually holds, which is not a given on seamless shapewear. There is no underwire, so it is support rather than lift, and if you want real lift you will still want a bra under something structured. But for wearing under a top or a dress, it is enough on its own.
Do I have to take the whole thing off to use the bathroom?
No. There is an opening at the bottom, which sounds like a tiny detail and is genuinely the difference between wearing it all day and giving up at lunch. If you have ever been most of the way undressed in a public bathroom stall because of a bodysuit, you already know why this is the feature I care about most.

How should it feel when you first put it on?
Snug, not painful. You should be able to take a full breath and sit down without the waist rolling. If it rolls down at the top or cuts a shelf into your thighs when you sit, that is a size too small and no amount of adjusting the hooks will fix it. If you can fit a flat hand comfortably under the waist and it still smooths, that is a size too big and you are not getting what you paid for.
Who this is not for
If you are looking for something to wear while you sleep or work out, this is not it, and shapewear is not meant to be worn around the clock anyway. If most of your wardrobe is thin and clingy, a smooth pull on style with no closure will sit better than a zip front. And if you are shopping specifically for back support, buy a back support garment, because this is a shaping bodysuit and it is not built to do that job.
If you are somewhere around 180 and you want the short answer so you can get on with your day, order the L/XL, measure your bust before you do, and check the back view in a mirror before you cut the tags.

Questions I get about this
What size shaping bodysuit do I need at 180 lbs?
The L/XL. The sizing runs doubled, so the choice at 180 is between L/XL and XL/2XL, and the L/XL still has the stretch to go on while keeping the compression. Move up to the XL/2XL only if your hips or bust sit at the top of the range or the leg openings dig in when you sit down.
Should I size up if I have a bigger bust?
Size for whichever of waist, hips and bust is your largest number, and on a zip up bodysuit that is very often the bust. The inner hooks let you add hold through the middle afterwards, but a zipper will not close over a cup size the size was not cut for.
Can you use the bathroom without taking it off?
Yes. There is an opening at the bottom, so you do not have to get out of the whole thing. It is the detail that decides whether you actually keep it on all day.
