Women's High-Waisted Swim Shorts: A UK Buying Guide

Finding swimwear that is comfortable, functional and flattering can feel like a challenge. For many, women's high waisted swim shorts offer the ideal solution, providing more coverage and security than traditional bikini bottoms. However, not all swim shorts are created equal. The market is filled with options that look promising online but fail to perform in practice, leading to wasted money and holiday discomfort. This guide will help you navigate the common purchasing pitfalls and identify the key features that truly matter.

Before you add a pair to your basket, be aware of these common issues:

• The Sagging Waistband: Many high-waisted styles rely on thin, weak elastic that rolls down, sags or loses its shape the moment you get active or hit the water. A secure fit quickly becomes a constant, frustrating adjustment.
• The "Quick Dry" Deception: A "quick dry" label is often applied to shorts made from thick, absorbent polyester that holds water for hours. This not only feels heavy and uncomfortable but can also lead to skin irritation and chafing.
• The Uncomfortable Liner: A built-in liner is meant to provide support and comfort, but a poorly designed one can be a major flaw. Liners made from the wrong material or with a restrictive cut can chafe, dig in and ruin your beach day.

Core Features to Scrutinise Before Buying

To ensure your new swim shorts are a reliable companion for swimming, sunbathing and sports, focus on these essential parameters.

1. Fabric: Material and Sun Protection

The fabric is the foundation of good swimwear. Look for shorts made from a lightweight blend of polyester and elastane (spandex). This combination offers durability, stretch and genuine quick-drying properties, as it doesn't absorb much water.

Crucially, check for a UPF 50+ swimwear rating. UPF (Ultraviolet Protection Factor) indicates how much UV radiation a fabric allows to reach your skin. A UPF 50+ rating blocks over 98% of the sun's harmful rays, providing reliable protection for the skin it covers. This is a property of the fabric's weave and is far more dependable than temporary spray-on sunscreens.

2. Construction: Waistband and Liner Design

A well-constructed pair of high waisted board shorts will feature a wide, flat elasticated waistband. This design distributes pressure evenly, preventing it from digging in or rolling over. For an even more secure fit, look for an adjustable drawstring that allows you to customise the tightness, ensuring your shorts stay put whether you're swimming laps or chasing a volleyball.

The quality of the swim shorts with liner is just as important. An effective liner should be a soft, stretchy brief made from a different, smoother material than the outer shorts. This two-part construction minimises friction and prevents chafing, offering comfortable support without the need for separate bikini bottoms.

3. Practicality: Pockets and Inseam Length

Functionality can make a good pair of swim shorts great. The inclusion of swimming shorts with pockets is a significant advantage, allowing you to carry small essentials like a key or card. For use in the water, pockets with a zip closure or a mesh lining are preferable, as they provide security and allow water to drain away easily.

Consider the inseam length that best suits your needs. A shorter inseam (around 5 inches) offers a classic look with great freedom of movement, while a longer inseam (7 inches or more) provides additional thigh coverage, reduces the chance of the shorts riding up during activity and is a common feature of board shorts for women. This is also a key consideration for those seeking comfortable plus size swim shorts.
