What counts as an underwear essential, and what should I start with?

Underwear essentials are the practical basics that go under your outfits — items like spencers (warm long-sleeve vests), half slips and cycle shorts. Start with what solves your most common problem: spencers for warmth, a half slip to stop skirts clinging or going see-through, and cycle shorts to prevent chafing under dresses and skirts.

What is a half slip and when do I need one?

A half slip is a lightweight underskirt worn under skirts and dresses to stop them clinging, riding up or showing through thinner fabric. It creates a smooth layer and adds modesty. You need one if your skirt or dress is light-coloured, sheer or static-prone — it's a simple fix for a common everyday problem.

What are cycle shorts for under dresses and skirts?

Cycle shorts (or anti-chafing shorts) are worn under dresses and skirts to prevent thighs rubbing and to add coverage and comfort, especially in warm weather. High-waisted styles also smooth the tummy. They're ideal if you find skirts uncomfortable in summer or want extra confidence and coverage when sitting or moving.

What is a spencer and when should I wear one?

A spencer is a warm, close-fitting long-sleeve or sleeveless vest worn as a base layer for extra warmth in cold weather. Wear one under jerseys, shirts and dresses on cold days to trap heat without bulk. It's a practical winter essential, especially in a cold home or for anyone who feels the cold easily.

How should underwear essentials fit?

Base layers like spencers and cycle shorts should fit close to the body so they layer smoothly and trap warmth or prevent chafing, so many shoppers choose their usual size. High-waisted cycle shorts should sit comfortably without digging in. Half slips should sit at the waist and fall to the right length under your skirt.

Which essentials help under light-coloured or thin clothing?

A half slip and a neutral camisole help under light or thin skirts and tops by adding an opaque layer that prevents see-through. Nude-toned essentials disappear under pale fabrics. For sheer or white clothing, choosing skin-tone essentials rather than white or black gives the smoothest, most invisible result underneath.

Should I choose cycle shorts or a half slip under a summer dress?

Cycle shorts are best if your main concern is thigh chafing and coverage when moving, while a half slip is better if the dress is clingy or see-through and you want a smooth drape. For a light, floaty dress in hot weather, many shoppers wear cycle shorts for comfort; choose based on the problem you're solving.

Can underwear essentials be returned if they don't fit?

Some base layers may have hygiene conditions for returns, so check PEP's current returns policy for the exact terms before buying — confirm in-store or online. Using the size guide first helps you choose the right fit, and keep tags and any packaging intact until you're sure the item works for you.
