One of the most common questions when shopping for swimwear is whether you should size up or down. Finding the perfect swimsuit can be challenging, but choosing the right size ensures you feel comfortable and confident all day at the beach or pool, regardless of whether you are in the water or on dry land.
So, understanding how to navigate swimwear sizing is key if you're eyeing high-waisted bikinis, one-piece swimsuits, or tankinis. In this blog post, we'll explore the ins and outs of swimwear sizing to help you choose the best fit for your body shape.
Swimwear Size Guide
When it comes to swimwear sizing, there isn't a one-size-fits-all approach. Swimsuit sizes tend to vary between brands, so it's crucial to consult the size chart provided by the manufacturer. However, some general guidelines apply across the board.
Band Sizing
Swimwear sizing often follows standard measurements, such as small, medium, large, or numerical sizes 6, 8, 10 and so on. These sizes generally correlate with body measurements, such as chest, waist and hip sizes. It's essential to check the individual brand's size chart to ensure you are getting the best fit, as just like most garments, the sizing can differ amongst brands.
Cup Sizing
Most swimwear brands offer sizing based on your cup size, especially for bikini tops, tankinis and swimsuits. If you have a larger bust, look for swimsuits designed to provide extra support. Adjustable straps and underwired bikini tops are great options for this. It may be worth sizing up to ensure comfort around the chest area without feeling too snug if you are in between sizes. The cup sizing for swimwear is similar to that of your bra sizing.
Does Swimwear Stretch?
There is no straight answer to this. One of the most important factors to consider when choosing swimwear is whether the fabric stretches. Many modern swimsuits are made from high-quality fabrics like spandex or lycra, which have a bit of stretch, allowing the swimsuit to mould to your body and provide a more comfortable fit. However, while the material does stretch to a certain extent, it's important not to rely solely on its elasticity. You still want your swimsuit to fit correctly before it starts to pull. A swimsuit that is too tight at the start may feel uncomfortable after you get wet, even if the fabric stretches out.
Is it Better for Swimwear to Be Tight or Loose?
The ideal swimsuit fit should feel snug but not restrictive. Swimwear is designed to hug your body and provide support, especially in the bust and waist areas. If the swimsuit is too tight, it may dig into your skin or cause discomfort, while a loose fit may result in an unflattering look and lack of support. For example, high-waisted bottoms can offer more coverage and support for the midsection, while adjustable straps on bikini tops allow you to customise the fit around the shoulders. You want your swimsuit to fit securely without feeling overly tight but snug enough to withstand the Australian surf.
Do Swimsuits Get Bigger or Smaller When Wet?
A common question when shopping for swimwear is whether swimsuits stretch when wet. The short answer is that most swimsuits expand slightly once they come into contact with water. This is particularly true for swimsuits made from natural fibres or certain fabrics that react to moisture. However, these fabrics usually return to their original shape once dry. That said, it's important not to base your size decision solely on this factor. It is best to choose a swimsuit that fits comfortably when dry, as this will give you a more accurate idea of how it will fit while wearing it.
