Berolloreb · Tried & Tested
"I read threads like this for several years with many people suggesting Boden and I thought it was just too expensive for something I don't wear much. However, having tried it I am a convert and when it is half-price it really isn't £££."

Our verdict

This stylish swimming costume from Boden is our pick for best overall swimsuit. Mumsnetters love the great quality fabric and subtle scaffolding underneath. The Santorini has lightly padded cups, a body-sculpting lining and a hidden support shelf under the boobs. What’s more, it holds its shape and the colours will stay bright all summer long. The straight neckline and halter-neck fastening are supremely flattering, and it’s available in eye-catching colour block, chic stripes, French navy and classic black.

"This was surprisingly flattering when I needed to quickly lay my hands on a costume recently I was worried it would be a bit old fashioned but the colour seems to lift it (I got purple) and the ruching isn’t too much."

Our verdict

With three body fits and a loyal Mumsnet fanbase, Lands’ End’s Tugless bathing suits are a real crowd pleaser. The secret to its success is the Lycra Xtra Life elastane in the fabric, which resists chlorine damage and keeps its shape for up to 10 times longer than other costumes. The fit is comfortable, practical and classic, with no bells and whistles. It’s got great bum coverage and, like the name suggests, it doesn’t budge.

TwinsPlusAnotherTwo · Tried & Tested
"I like their swimwear - I ordered loads from there last year to get a choice, and thought it was all good quality. Lots of the designs have both bikini and tankini tops - buy one of each and you can choose whether to go for a bikini or cover up a bit more." 
See Post
Our verdict

Tankinis are brilliant for getting just the right fit top and bottom, and this one from Curvy Kate is blessed with underwire support and fully adjustable, non-slip straps. Fitting like a proper, unpadded bra, it’s a godsend for the big of boob, and stands up to regular pool swimming. Mumsnetters recommend ordering a few sizes to figure out a perfect fit.

How to buy the right swimsuit for your body type

Just like with clothes, it’s important to find a swimsuit or swimwear collection that you feel like yourself in. Go for what makes you feel comfortable. If there are parts of your body you feel less confident about, look for a swimming costume that offers support or coverage in these areas.

What’s the most flattering type of swimsuit to wear?

When you feel confident, you naturally look your best. The most flattering swimsuit is a swimsuit you feel good in.

Do you need different swimsuits for different activities?

Not necessarily, but if you’re a regular pool swimmer you’ll want a practical swimsuit that’s resistant to chlorine damage - like the Arena LighTech or Lands’ End Tugless. For holidays you might want a more stylish swimsuit that can double up as a top, like one from Batoko or the Boden Santorini.

What’s the best swimsuit to buy?

Boden’s Santorini swimsuit is the top swimsuit to buy according to Mumsnet users - it ticks all the boxes for style, quality and practicality.
