The Ultimate Guide to Choosing the Best Slip Shorts: Undersummers vs. Thigh Society vs. Other Brands

Slip shorts have become a staple in many wardrobes, offering a comfortable, seamless, and stylish solution to prevent thigh chafing, ensure modesty, and enhance the fit of clothes. With many brands on the market, it can be challenging to decide which pair is right for you. 

Undersummers and Thigh Society have enhanced women's thighs since the early 2000s, bringing exceptional fit and function to the marketplace. Both brands use lightweight, cool, moisture-wicking fabrics with size-inclusive sizing. Undersummers favors fashion and fun, while Thigh Society neutralizes the slip short.  Both are great options, and we at Undersummers are happy to share this thigh-loving space with Thigh Society.

This blog was written to help you understand the similarities and differences between slip short brands so that you can choose the slip short shortlettes that are right for you.

What To Consider When Choosing Your Fave Slip Shorts Brand

Slip Short Comfort and Fit

Undersummers shortlette slip shorts are renowned for their comfort and perfect fit. Designed with a stretchy, soft fabric that moves with your body, they provide a breathable, non-constricting feel, making them ideal for all-day wear. The lace trim adds a feminine touch and prevents the shorts from rolling up or down - something you don’t find with other brands.

Thigh Society slip horts also score high on comfort. They feature a lightweight, moisture-wicking material that feels like a second skin. The high waistband is designed to stay put without digging in, ensuring a smooth silhouette under clothing.

Other Brands: While numerous other options are on the market, not all offer the same level of comfort and fit. It's important to look for features such as a non-rolling waistband, breathable fabrics, and a fit that complements your body shape, which are key indicators of quality.

Our Pick: Undersummers or Thigh Society. Both brands offer supreme comfort and incredible fit. Both brands won’t ride down, roll up, or dig into you, offering a feels-like-nothing underwear solution that you can trust day after day.

Material Quality

Undersummers utilizes a high-quality, soft fabric that is both stretchy and durable with moisture-wicking properties to keep you cool. This material is designed to withstand frequent washing without losing shape or comfort.

Thigh Society opts for a microfiber blend that is ultra-soft and designed for breathability. This ensures you stay dry and comfortable, even on the hottest days.

Other brands vary significantly in material quality. When comparing brand to brand, check for stretch, durability, and moisture management materials to ensure a comfortable experience.

Our Pick: Undersummers - the material that makes an Undersummers shortlette is built to last year after year. Although Thigh Society uses similar quality materials to keep you cool, we believe in getting more bang for your buck. Undersummers slip shorts keep you cool AND keep their shape, offering you the ability to save more money in the long run, not having to rebuy your slip shorts every summer season.

Variety and Style

Undersummers offers a wide variety of colors and patterns, allowing you to choose a style that best fits your personality and wardrobe needs. They also provide different lengths, catering to various body types and preferences.

Thigh Society focuses on a more streamlined selection, emphasizing neutral colors that blend seamlessly under clothing. Their focus is on functionality and comfort, with less emphasis on fashion.

Other brands may offer a range of styles and colors. However, the selection can vary greatly, so it's worth exploring multiple brands to find your perfect match.

Our Pick: Undersummers, Thigh Society, or any other brand on the market. It’s truly up to you, your style, and your personality. We encourage you to try all options and lengths.

Durability and Care

As mentioned before, Undersummers are designed to last and are made from high-quality materials that maintain their integrity even after multiple washes. (They recommend gentle washing to prolong the life of their shorts.)

Thigh Society also emphasizes durability, with its shorts designed to maintain shape and quality over time. They, too, suggest gentle care for their products.

Other brands' durability can vary, making it essential to read reviews and care instructions carefully before making a purchase.

Our Pick: Undersummers, but Thigh Society is close behind. Both brands offer long-lasting durability, but we’ve seen Undersummers last longer. Call it bias, but we call it experience. When deciding between the two, we’ve chosen the one we’ve had the most time with.

Women-Owned Business

Both Undersummers and Thigh Society are women-owned businesses. Why does this matter? Because you want to buy a product made for women from women designers who need the same solution - a moisture-wicking, ultra-comfortable, no-slip, no-roll-up slip short to go under every dress and skirt. 

As for other brands, you may find that they are also women-owned you just have to do your research if this is important to you. 

Our Pick: If you want to buy a product made for women by women, you can’t go wrong with either Undersummers or Thigh Society, or any other brand you find with women founders, owners, and designers. If you care to buy from USA manufacturers, Undersummers is the brand for you, as Thigh Society manufactures overseas in China.

Price Point

Undersummers and Thigh Society are positioned at a premium price point, reflecting their quality, comfort, and durability. While some may find them an investment, many users find the cost justified by the product's longevity and performance.

Other brands offer a range of price points. Lower-priced options might appeal to those on a budget, but it's essential to consider the potential trade-offs in quality and durability.

Our Pick: Again, it’s up to you… Just remember, you get what you pay for. If you want quality, trusted reviews, durability, and style, you can find that with Undersummers, Thigh Society, and other brands. If you want a cheaper solution to fit one-time needs, you can find that no problem. It depends on what you want to pay for and how willing you are to buy again if a chosen shortlette falls short.


When choosing the right slip shorts, considering comfort, material quality, variety, durability, and price is key. Undersummers and Thigh Society offers exceptional products catering to different preferences and needs. By carefully evaluating what's most important to you in a pair of slip shorts, you can select a brand that offers the best fit, comfort, and value for your lifestyle.

Meet our founder: CarrieRae

Undersummers Shortlettes were created CarrieRae's personal need for comfortable thigh protection when she was working as a teacher. In 2011, her thick thighs rubbed and she needed a comfortable solution.  Pants are blazing hot in the Houston spring/summer months, shorts are not acceptable to wear to work, so she was left with capris and dresses.  Her thighs did not support wearing dresses, thigh chafing was too uncomfortable.  The idea of wearing a breezy dress sounded so comfortable to her, that she created the solution to her problem:  The Original Lace Shortlette®️. She wanted something to wear that was a single layer, the legs stayed put, comfy, and most importantly, pretty.
