How Size 18W Swimwear Works

Treat 18W as its own cut when comparing the measurements. It is not another spelling of regular 18. Start with your usual clothing size and read the complete product option.

A Comfortable Fit Check for Size 18W

Check the swim dress at the waist and through the body as you sit and move. Read the style's measurements and length guidance where supplied. The number alone does not describe the cut.

Fuller Bust Support When Choosing Size 18W

For fuller busts, explore the Swimwear Size Chart and the Cup-Sized Bikini Size Chart. Read the individual product's chart and construction details before choosing.

Frequently Asked Questions About Size 18W Swimwear

How do I assess the fit of a size 18W swim dress?

Start with your usual clothing size and check the swim dress's own chart if you are between sizes. Sit and move to assess the fit at the waist and through the body, using length guidance where supplied.

What should I check before changing size 18W?

Notice where the fit feels restricted or loose, then compare the individual style's measurements and cut. More strap tension does not add room through the body.
