I work for Calida in the US and I’m sorry you didn’t have luck with our famous Lycra Lace briefs.
If this brief is riding up, and with the information provided regarding your profile, it sounds like you are ordering the wrong size.
These panties are seamless (no side seams) and should conform to your body shape. However, if you are not satisfied with this style, may I suggest you try style 23024 Comfort stretch cotton. This panty has more back coverage and stretch.
We thank you for trying our products and appreciate your comments!
