The Marilyn tucks your Sig Sauer under your arm and out of sight. It fits best with compact models like the P238, P938, and ROSE P365 .380, and it is a great option for dresses, scrubs, or any day when a waistband holster is not going to work. It is also available for medium-frame Sig pistols including the P365 family and P365-XL, and works well for many women depending on body type and bra fit.
