OnThatAss is an innovative and exciting subscription service that brings a touch of fun and surprise to your underwear drawer. Specialising in monthly deliveries of exclusive, high-quality boxers for men and sets for women, this brand dares you to embrace bold styles and comfortable fits that keep you feeling fresh and confident every day. Whether you’re looking to refresh your wardrobe with something unexpected or simply enjoy the thrill of unboxing a mystery item, OnThatAss delivers premium undergarments straight to your door, making it a favourite among UK shoppers seeking convenience and excitement in their daily essentials.

What is OnThatAss?

OnThatAss is a subscription-based brand dedicated to revolutionising the way people experience underwear. Launched with a mission to inject personality and surprise into everyday wear, it offers tailored plans for both men and women, ensuring everyone can find a fit that suits their lifestyle. The core idea is simple yet captivating: sign up, get your first item completely free, and then receive a curated surprise every month that encourages you to step out of your comfort zone.

At its heart, OnThatAss combines quality craftsmanship with a playful ethos, sourcing materials that prioritise comfort, durability, and style. For men, this means boxers designed for all-day wear, while women receive elegant sets that blend sophistication with a dash of daring. The brand’s name alone hints at its cheeky, confident vibe, appealing to those who want undergarments that match their bold personality without compromising on practicality.

What sets OnThatAss apart in the crowded intimates market is its focus on exclusivity – each delivery is a one-of-a-kind item not available in stores, ensuring subscribers always have something fresh and unique. With easy online account management for login and sign-up, getting started is straightforward, making it accessible for busy UK professionals and fashion enthusiasts alike.

Products and Services

OnThatAss provides a streamlined range of subscription services tailored specifically for men and women, eliminating the hassle of shopping for underwear. The men’s plan delivers premium boxers that are soft, breathable, and stylish, perfect for active lifestyles or casual days. Meanwhile, the women’s option sends exclusive lingerie sets featuring matching bras and panties crafted from high-end fabrics like cotton blends and lace accents.

Both subscriptions follow a try-before-you-buy model, starting with a complimentary first item upon joining. Subsequent months bring a mystery delivery – think vibrant patterns, seasonal themes, or limited-edition designs that keep your collection evolving. All products are discreetly packaged and shipped directly to your UK address, with options to pause, skip, or cancel anytime for maximum flexibility.

  • Men’s Boxer Subscription: Focuses on durable, comfortable fits with a variety of cuts, from classic to athletic, ensuring versatility for every body type.
  • Women’s Lingerie Set Subscription: Offers coordinated pieces that emphasise elegance and confidence, with sizes ranging from petite to plus for inclusive appeal.
  • Customisation Options: Subscribers can select preferences like size, style hints, or even dietary allergies for fabrics, personalising the surprise element without losing the excitement.

This service-oriented approach means OnThatAss isn’t just selling products; it’s curating an ongoing experience that fits seamlessly into your routine.

Key Features

One of the standout features of OnThatAss is its free introductory offer, which removes any risk for new members and encourages trial without commitment. The monthly surprise box adds an element of anticipation and delight, turning a mundane purchase into a highlight of the month. Packaging is always eco-friendly and discreet, aligning with UK standards for sustainable shopping and privacy.

Quality control is paramount, with every item undergoing rigorous testing for softness, stretch, and longevity, so you can trust that your subscription delivers value month after month. The online platform is user-friendly, featuring secure login, easy profile updates, and transparent billing that avoids hidden fees. Additionally, OnThatAss emphasises inclusivity by offering a wide size range and diverse style options, catering to all preferences and body types across the UK.

Another key aspect is the brand’s commitment to surprise without overwhelm – deliveries are limited to one item per month, preventing wardrobe overload while keeping costs predictable and affordable.

Benefits

Choosing OnThatAss means enjoying unmatched convenience in sourcing high-quality underwear, saving you time and effort on trips to the high street or endless online browsing. The subscription model ensures you never run out of fresh pairs, promoting better hygiene and confidence in your daily wear. UK customers particularly appreciate the reliable delivery and competitive value, often finding it more economical than buying individually from premium retailers.

Beyond practicality, the excitement factor boosts customer satisfaction, with many reporting a fun twist to their routine that enhances self-esteem. For those mindful of budgets, the free starter item and steady monthly pricing help stretch your pounds further, especially when paired with smart shopping tools. Looking to save even more on OnThatAss purchases? BudgetFitter helps UK shoppers track the latest deals and discounts. You can find exclusive offers through the BudgetFitter website, browser extension, or mobile app, making it easier to maximise value on your subscription.

Overall, OnThatAss empowers subscribers with quality assurance and personalised surprises, fostering loyalty through consistent excellence and a brand ethos that’s as bold as its name.

History and Background

OnThatAss was founded in the early 2010s by a team of fashion enthusiasts tired of bland underwear options dominating the market. Starting as a small online venture in Europe, the brand quickly gained traction for its innovative subscription model, expanding to serve international customers including a strong UK base. The founders drew inspiration from mystery box trends in other industries, adapting it to intimates to create a niche that’s both practical and playful.

Over the years, OnThatAss has grown by prioritising customer feedback, refining product selections and shipping logistics to meet high standards. Key milestones include launching gender-specific plans and introducing sustainable materials in response to eco-conscious demands. Today, it’s recognised as a forward-thinking brand that blends British humour with European design flair, continuing to evolve with trends like inclusive sizing and ethical sourcing.

This rich background underscores OnThatAss‘s dedication to innovation, ensuring it remains a go-to for those seeking more than just basics in their underwear collection.

Special Offers and Savings

OnThatAss regularly rolls out promotions to enhance affordability, such as extended free trials or bundled first-month deals starting from as low as nothing out of pocket. These offers make it easy for new subscribers to dive in without financial hesitation, often including up to 50% savings on initial shipments compared to retail prices. Seasonal campaigns, like back-to-school or holiday surprises, further sweeten the deal with bonus items or discounts on upgrades.

For ongoing value, the subscription itself provides built-in savings through bulk-like pricing without the bulk purchase commitment, ideal for budget-savvy UK households. Savvy shoppers can amplify these benefits by monitoring flash sales or referral programmes that reward sharing the love. For the best OnThatAss deals, BudgetFitter is an invaluable resource, helping you discover verified promotions and track price drops via our website, browser extension, and mobile app – ensuring you never miss out on exclusive savings tailored for UK users.

By leveraging these opportunities, customers not only enjoy premium products but also stretch their budgets further, making OnThatAss a smart, enjoyable choice for long-term wardrobe investment.
