My recommendation is to not use "Jeans" in the logo for the simple reason that is not a part of the name. It is the products.
Comparison: Nike sells shoes, clothes and a lot of other stuff. They are not called "NIKE Shoes" in all branding/advertisment. They're simply "NIKE" or just the "SwooshS icon.
Focus on the special name and build a logo that really says : "GLAM"! In all your campaigns you then can add that it is about jeans in photos, text or illustrations. Let people themselves associate like: "GLAM"... hmm that's jeans.. isn't it?
