These Spanx OnCore Shorts was just the product I needed when I attended a wedding this past weekend. I like how easy it was to put on the shorts and the instant slimming effect they provided. First time using Spanx and certainly not the last. I like how the material hugged my body but not in a suffocating way. The panels inside the shorts flattened my stomach in all the right places. I also like how discrete this shaper is and I had no visible panty lines. The material feels great and seems to be very good quality. I highly recommend these Spanx for instant sculpting/smoothing for any occasion.

I really wanted to like this product. Spanx is a well known brand, and product seems to be well liked. Let’s start with the pluses. 1. The material is so soft and smooth. 2. It has a slit in the pelvic area so that you can use the bathroom. Here are the cons 1. The slit to pee from is weird. You would have to pull it apart, so you don’t pee on the shorts. 2. It was horrible to put on. I know if I had fake nails, I would have never been able to get it on. 3. It’s way too long. I have a long torso and short legs. Realistically the shirts were so I long, I could have just worn it as a body suit. When I sat down, that extra fabric just dug into my waist and ribs. Unfortunately, I do not recommend this product. If it was a lot cheaper, then maybe, but for the price and ... MoreI really wanted to like this product. Spanx is a well known brand, and product seems to be well liked.

Buy your true SPANX size

Sooo comfortable & thinner than the original Spanx.These are true to size - don’t size up like you had to with the original Spanx. Refer to Spanx size chart to verify the right size needed. I’m a 6 which is a Spanx Medium (not a small) & they’re perfect.They stay upDo not rollAre invisible under tight winter white Ann Taylor trousersAre amazingly comfortable for what they areI wear these over Chantelle’s one size fit most hipsters without any lines or problems.

Felt my best in my wedding dress!

[This reviewer is a Spanx employee and received a gift in exchange for helping other Spanx shoppers.] I wore these shorts under my wedding dress and I felt confident in a tight, white dress all day! Not only were they flattering, they were so comfortable and I didn't think twice about them once they were on. My bridesmaids, mom, and mother-in-law all also wore their Spanx shapewear on the big day! PLUS, I now wear them under many other dresses day-to-day for some extra support!

Missing a Few Key Features

These On Core Shorts are a somewhat good design, as the leg comes down a little lower on the thigh, at least, and there’s some smoothing of the entire region.The color is good and the material has just enough slip to wear under clingy garments without everything sticking together.They generally seem well made, but are lacking in a few important areas.There is no adhesive kind of thing at the thigh cuff, unfortunately, or some feature to keep them in place without creating an indentation. There’s nothing to keep them from rolling up under leggings or tight jeans, etc., either. The waistband has a similar problem, but it will roll down.We don’t wear these things to have them be visible, so it defeats the purpose when the undergarment will end up showing under ... MoreThese On Core Shorts are a somewhat good design, as the leg comes down a little lower on the thigh, at least, and there’s some smoothing of the entire region.The color is good and the material has just enough slip to wear under clingy garments without everything sticking together.They generally seem well made, but are lacking in a few important areas.There is no adhesive kind of thing at the thigh cuff, unfortunately, or some feature to keep them in place without creating an indentation.

Price discrepancy

Biggest concern is that the Spanx tag on the item says $32 and Anthro is charging $64! Double the price?! That alone guarantees a return; I will buy directly from Spanx next time. The product itself runs pretty snug (yes, they’re Spanx, but much smaller than other Spanx products I own). Also, description says there is an open gusset between the legs for going to the bathroom but these do not have an opening.

Size up 1-2 esp if you have a tummy

My details: 5'5, ~197lbs, size 12/14. Bought these in XLIf you don't have a flat stomach, size up 1-2 sizes. I expected these to be snug (as shapewear is supposed to be) but they instantly rolled. I was able to hike them up almost up to under my bra but as soon as you start moving around, they start sliding down and instantly roll again. XL is the largest size they offer or else I'd exchange. Bummed because they seemed to fit well otherwise but waistband is too contoured and having a muffin top from shapewear almost makes the issue worse.

Smooths out all my imperfections

I can definitely tell the difference with and without wearing these. It makes my clothes sit nicely and doesn’t show all my lumps and bumps. I feel a lot more confident wearing more fitted clothes with these underneath. I wish they were another inch longer though. I’d buy again.

Spanks for the win!

I bought these to wear under dresses to smooth me out. This definitely does the trick without panty lines! I was a bit skeptical about the shorts component and turns out it was exactly what I needed. Sizing was intimidating. I'm 5'8.5", 170, and wear a size 8 pant. I tried the large and medium. While the large was definitely more comfortable, the medium is what created the tight shape I desired. The ladies in the store told me to go with my normal size (medium). They were right! (Thanks ladies!). Highly recommend.

cut in at the top

I got this to wear under a form fitting bridesmaids dress and I didn't end up wearing it. I got my regular size and should've sized up because it cut in at the top and instead of being smoothing it gave me a muffin top above the top of the shorts. The material was high quality but the fit totally defeated the purpose of getting them in the first place. These would probably work best for an hourglass shape as opposed to someone who carries their weight in the middle.
