3X/4X Back Seam Panties

HerRoom has a large selection of women’s underwear from hundreds of panty brands that can flatter your figure and work with your outfits. Whether you prefer full-coverage underwear like briefs, boyshorts and bikinis or sexy panties like thongs, g-strings, and crotchless panties, we have a style for every size and shape. You can also choose from a range of fabrics and materials like breathable cotton, lovely lace, smooth satin, leak proof fabrics and more. 

When selecting the best panties for everyday wear, you want to look for a style that is comfortable and non-binding, with coverage that makes you feel supported without showing obvious panty lines. 

Check out our Panty Styles Guide or watch our video “Best Panty Styles for Your Bottom Type” for help finding the best type of women’s underwear for you.

Panties should fit your contours without creeping up. Once the elastic is shot, they look dingy, or they become stretched out and no longer stay in place, they should be replaced. When that time comes, determining your panty size for new underwear requires that you know two things: your waist measurement and your hip measurement.

Check out our Panty Fitting Guide for information on how to measure your size and how to check that you’ve got the best fit.

Properly caring for your panties will help keep them looking fresh and fitting well for a longer time. Using gentle laundering methods can reduce wear on the elasticity of your underwear and protect the quality.
