Frequently Asked Questions
Will seamless boyshorts totally eliminate panty lines?
Seamless boyshorts greatly reduce visible lines because they remove raised seams at the leg and have bonded or soft hems. However, the final result depends on the dress fabric and fit — thin clingy fabrics or very tight silhouettes may still show slight lines unless the dress is lined or a slip is used.
Should I choose underwear with compression to hide lines?
Light to moderate compression can smooth the silhouette and reduce lumps that create shadows under a dress. Avoid very high compression if it digs into skin — that can create new lines. Look for garments labeled light tummy control or moderate shaping for holiday wear.
What fabrics and linings hide underwear lines best?
Heavier, tightly woven fabrics like crepe, thicker satin, or lined knits disguise seams best. Dresses with a built-in lining are ideal. If your dress is thin, add a slip in a matching color to create a continuous, non-clingy layer that prevents the outer fabric from showing the underwear’s texture.
