FAQ Plus & Extended Size Swimwear
What is plus size vs. extended size swimwear?
Plus size swimwear typically refers to sizes above standard ranges, often starting at XL or 1X. Extended size swimwear goes beyond traditional sizing on both ends of the spectrum—offering more inclusive options for a wider range of body types. At Watermen, we offer extended size swimwear ranging from XL up to 6X, ensuring everyone can find a comfortable, confidence-boosting fit.
Who is extended size swimwear designed for?
Extended size swimwear is designed for people of all body shapes who fall outside traditional size charts. It provides improved fit, comfort, and support compared to standard sizing. Watermen’s extended sizing ensures your entire crew—men, women, and youth—can all be outfitted in premium plus size swimwear without compromise.
What size range do you offer for men’s and women’s swimwear?
Watermen offers men's & women's plus and extended size swimwear up to 6X. Our inclusive range is built to accommodate diverse body types. For the most accurate fit, we recommend referencing our detailed size chart with exact measurements.
How do I find the right size swimsuit for my body?
To find your best fit, measure your:
- Bust or chest
- Waist
- Hips
- Torso (for one piece swimsuits)
Compare your measurements to the Watermen size chart. If you fall between sizes, we typically recommend sizing up for optimal comfort and coverage.
Are there adjustable waist options for men’s and women’s swimwear?
Yes. All Watermen men’s and women’s e-waist trunks and boardshorts feature an adjustable drawstring waistband for a secure, customizable fit. Additionally, women’s bikini bottoms include a drawstring waistband, allowing for better flexibility and comfort.
Will the fabric stretch out over time?
Watermen uses premium stretch fabrics designed to retain their shape over time. Proper care—such as rinsing after use and following care instructions—helps maintain fit, elasticity, and longevity.
Can I mix and match sizes for tops and bottoms?
Yes. All Watermen swimwear pieces are sold individually, allowing you to mix and match sizes for tops and bottoms. This ensures a customized fit—especially helpful for bikinis for big busts and different body proportions.
