Based on over 15,000 Amazon reviews, these shapewear shorts flatten the stomach, bring in your waistline, and are the perfect undergarment for dresses. They're essentially the best shapewear and the best anti-chafing shorts rolled into one. The shorts are stretchy and breathable, but run small, so the brand recommends sizing up. This has been a well-loved choice amongst buyers, with one calling it: "the most comfortable and effective shapewear I have."
Finding quality shapewear that's seamless and doesn't roll down is hard to come by. Fortunately, these shorts are constructed with four steel-like brackets that keep the garment up on your waist.

This shapewear slip has a firm fit that pulls everything in and smooths out any bumps under your clothing. And it has an open-bust design, allowing you to wear your best bra with it.
This slip is the perfect undergarment to wear underneath fitted dresses. It brings in your waist, flattens your stomach, and gives you a slimmer appearance. If you need a bit of a confidence boost, this slip is a great alternative to dresses to hide a tummy. woman&home's Fashion Ecommerce Editor Caroline Parr is a big fan too: ''Spanx really is the best in the business, and there's a reason it's the first brand that springs to mind when you think of shapewear. A slip is brilliant for underneath dresses, as it gives you that smoothing effect, but in my opinion is much more comfortable than shorts or a bodysuit.''

How to choose the best shapewear for you
When it comes to choosing the best shapewear for you, it's essential that you consider the specific areas you want to enhance, cover, sculpt, or support. Stylist and owner of Room Seven, Harriet Fitzpatrick, says the type of shapewear you need varies depending on your preferences. "You have briefs, bodysuits, slips, shorts, thongs, and they all carry different levels of coverage."
For those seeking full coverage, Fitzpatrick recommends opting for a bodysuit or slip. These pieces will provide comprehensive support and smooth your silhouette, which flatters your curves. Full coverage is ideal if you want to wear a dress, skirt or any tight-fitting outfit, and can help you achieve a flawless look with confidence.
And if you're targeting the stomach, hips, or waist, depending on the rise, she recommends briefs and thongs shapewear. Briefs can offer moderate coverage and support, which enhances the way you look and feel all day long. They are also more suitable to wear all day as they are less restrictive than a bodysuit. Thongs can provide targeted shaping without a visible underwear line, ideal if you want to wear a tight-fitted skirt or dress.
For those looking to enhance and tone their bum, briefs and shorts are best. They can sculpt and lift your bum, providing a flattering and natural-looking lift. Through establishing what area you want to target, you can choose the right fit, which should help you look and feel your best.
FAQs
Should you size up or down in shapewear?
Fitzpatrick says it all depends on the brand. "Some of the better quality brands run smaller, and you have to size up," she says. "And some of the cheaper brands require sizing down. Again, it will depend on the brand. But it is important to look at the size chart to determine what's best for you."
Should you wear underwear with shapewear?
Whether you wear underwear with your shapewear depends on your personal preference. Some shapewear is supposed to be worn without underwear - the ones with built-in liners or those which have bust control - whereas some shapewear does not have built-in coverage or support. If you would like an extra layer of protection, you can certainly wear underwear underneath. Additionally, be mindful of which underwear you choose, and make sure you select pieces which complement the shape you are trying to achieve and are not visible.
How do you wash shapewear?
There is lots of speculation about washing shapewear the correct way, and this is because you don't want it to lose elasticity. If your shapewear is machine washable, it's advised that you set your washing machine to a delicate or gentle cycle, then place the piece in a mesh bag (use a pillowcase if you don't have a mesh bag), then wash on a cool setting. Also, use a gentle detergent that's free from bleach.
What firmness should you have for shapewear?
When choosing the firmness of your shapewear, consider comfort first. Of course, the piece needs to sculpt your target areas, but make sure it fits comfortably, too. Light compression is ideal for everyday wear, and firmer compression may be suitable for formal events or when wearing body-fitting outfits. It is good to experiment and try a variety of options to find the perfect balance between support and comfort.
