Trend Guide: Thong Swimwear, High-Cut Bikinis and Tan-Through Swimwear – Summer in Ireland
Surprise: the thong swimsuit is making a comeback at Ireland’s beaches, lidos and outdoor pools. This guide looks at the trends around thong swimwear, high-cut bikinis and tan-through swimwear for an Irish summer: what people are wearing, why these choices are popular, how to choose styles for different body shapes, and how to care for these pieces properly.
Choosing swimwear in Ireland is often about balancing style with real-world comfort: wind, cooler water, and short windows of strong sunshine can all influence what feels wearable. Modern cuts like thong backs and high-cut legs can look minimal, but the details—lining, straps, and fabric weight—make the difference between a confident fit and constant readjusting.
The comeback of thong swimwear: what makes it so popular?
Thong swimwear has returned largely because it aligns with today’s preference for cleaner lines and less visible fabric under cover-ups. Many designs now rely on more structured materials than earlier versions: double-layered backs, wider elastic at the waist, and contoured seams that reduce digging-in. This makes the silhouette feel intentional rather than purely revealing, which helps explain why it shows up in both trend-led collections and performance-inspired ranges.
Popularity is also tied to how thong cuts interact with movement and tanning. With less fabric at the back, there’s less chance of bunching when walking, swimming, or sitting on a towel. That said, comfort is highly individual: a thong bottom that feels secure on the beach can feel different after a dip in colder water, when fabric stiffens slightly and elastics may feel tighter.
High-cut bikinis: cuts and styling tips
A high-cut bikini refers to a higher leg opening that sits above the hip bone, creating a longer leg line. In practical terms, it can also reduce bunching at the crease of the thigh—useful for walking along uneven sand or climbing steps at sea pools. The most wearable versions tend to have a slightly wider side band and a stable waist edge, so the cut stays consistent rather than creeping upward.
For styling, it helps to separate “high-cut” from “high-waisted.” You can have a high-cut bottom with a mid-rise waist, which often feels more secure for beach walks in breezy conditions. If you prefer more coverage, look for high-cut bottoms that still offer a broader front panel and a fully lined construction. Pairing a high-cut bottom with a simple triangle, balconette, or sporty crop-style top can also balance proportions and support.
Fit and wear: practical aspects of modern swimwear
In Ireland, many people buy swimwear from a mix of local high-street retailers and widely available online stores, especially when looking for specific cuts (thong backs, high-cut legs) or fabric features (quick-dry, textured, or tan-through options). Availability can vary by season and size range, so it can be useful to compare fit notes, return policies, and whether styles are designed for pool use, sea swimming, or sunbathing.

Fit comes down to three checkpoints: stability, coverage where you want it, and fabric behaviour when wet. For thong and high-cut shapes, stability usually depends on the waist elastic and the gusset width. A narrow gusset or thin elastic can feel “floaty” on land and may shift after swimming. Adjustable side ties can help fine-tune fit, but they also introduce knots that can press into the hip when lying down.
Tan-through swimwear adds another layer of decision-making. These fabrics are typically engineered with micro-perforations or special knits that allow more light through than standard swim material. They can feel lighter and more breathable, but they are not a substitute for sun protection. In Irish conditions, it’s also worth noting that lighter, more open knits can feel cooler in wind and may show more texture when wet. If you’re considering tan-through styles, check opacity in bright light and confirm whether the garment is fully lined.
Practical wear also includes where you plan to swim. Sea swimming and sea pools can mean rougher surfaces, cold water, and more movement getting in and out. For these settings, look for stronger stitching at stress points, secure straps (especially for halter and bandeau tops), and fabrics that recover shape after exposure to saltwater. Rinsing after use and drying out of direct heat can help maintain elasticity, which is particularly important for minimal cuts where a small loss of tension changes the fit.
Finally, comfort isn’t only physical—it’s situational. A thong back or very high-cut leg might feel perfect for a quiet spot on a warm day, and less ideal on a crowded promenade or a windy beach. Many people solve this by treating swimwear as a base layer: add a wrap skirt, loose shorts, or an oversized shirt for quick coverage without changing the overall look.
Modern swimwear trends can be worn in a practical way in Ireland by focusing on construction and context rather than the label on the cut. Thong and high-cut styles can feel secure and comfortable when the waist edge, lining, and strap design are right, while tan-through fabrics may suit sunbathing but still require careful attention to opacity and sun safety. The most reliable approach is choosing a fit that stays stable when wet and matches how—and where—you actually spend your summer days.
