Everything You Need To Know About Buying Swimwear Online

Let’s be honest: the changing room experience does nothing for the already tender task of test-driving a bathing suit. Ordering swimwear online allows for a more relaxed try-on session at home, plus it opens up a whole world of options that might better suit your body, budget and style inclinations. On the flip side, taking the leap and buying a swimsuit without trying it on first comes with its own challenges: relying on a size chart to find the perfect fit, taking a chance on an unfamiliar cut and forgoing the hand feel. Here, all the insider advice you need to feel confident buying your next bather online.

How do I find my size when shopping online?

Hands up if you’ve ever faced sizing woes in the swimsuit department. With no standardized measure of size across brands, buying online can be tricky. Your best bet is to consult the size chart. This resource will often provide three points of reference to work from: the bust, the waist and the hips (which, by the way, should be taken at the widest part of your bum.) Don’t have a soft tape measure handy? Use a length of string to take your dimensions, then compare against a ruler or measuring tape. The most accurate reading will be one that comfortably rests against your skin—you want to be able to breathe normally without the tape digging in.

What’s the best swimsuit material to look for?

Most swimwear is made up of a combination of nylon (sometimes referred to as polyamide) and lycra or elastane (the fabric that gives a suit its stretch). The best ratio to ensure both comfort and longevity is around an 80-20 split: you want your swimsuit to have some give, but return back to its original shape easily. Other factors like printing and the weight of the fabric, which isn’t always apparent in pictures, could also result in a tighter, more constrictive fit. Another thing to think about: how sheer your swimsuit might appear after a dip. Pictures can provide helpful hints and, when in doubt, reaching out to customer service representatives or indie brands’ founders is also a good option.

What’s the best swimsuit top for my bust?

First, consider your desired result. If you’re looking to add a bit of oomph up top, exercise caution with cup inserts. Smaller busts might benefit from front seaming on bralette-style shapes instead; the little notches add structure and give the illusion of a fuller cup. A sports-style top is a good pick for bigger chests, but if you want to avoid the compressed look, opt for a wide band under the bust, as well as a tie-back closure that criss-crosses your back. These two design elements offer comfort-first support by eliminating pressure from the neck and evenly distributing it across the shoulders. And while a minimal shelf bra—the built-in bra lining that often accompanies a one-piece—might look like it’s better suited to petite chests, it’s actually a perfect option for ample cup sizes.

What design details should I look for in a swimsuit?

Give thought to what sort of activities you’ll be doing in your swimsuit; true function should be top of mind. If you’re the lounge-all-day type, tie fastenings might not be the most comfortable choice while laying on your back. If you’re more drawn to water sports, no-slip leg openings and a higher neck will ensure that your suit stays in place.

Adjustability features can also help ensure a custom fit. Our bodies are all different, so having that ability to tighten up some straps and shorten the torso is great. Pay attention to product descriptions for these kinds of elements—sometimes it takes reflecting on your swimsuit hang-ups to understand what you should look for. Think about the things you don’t like in a bathing suit and go from there. Always feel like your bandeau’s slipping? Find one with stay-put silicone gumming. Concerned about bulging? A flexible tie-back closure will allow you to modify the suit to your size.

How do I find a swimsuit that won’t go out of style?

Keep it simple, who’s a big fan of the classic one-piece maillot. It’s such a timeless, versatile piece. It really takes you from water to land with ease. You can throw on a pair of jean shorts or a skirt and wear it as a full look.

The high-waisted bottoms trend isn’t going anywhere either. And for good reason: this cut delivers a figure-defining shape and uncompromising security. When it comes to bikinis, opt for colours that allow you to mix and match effortlessly. This kind of wearability let’s you double or triple your two-piece possibilities, a smart move considering our cooler climate often means we assemble a leaner swimwear wardrobe.
