It was a cute gift, and she really did mis-handle the situation. If anything, it was a size or two too big. She could've easily just said, "Oh, thank you so much" and kept her comments to herself, to avoid hurting Jenna's feelings, because it's obvious Jenna kind of shrunk into herself when Jessel said those things. Plus, Erin was right: you haven't had sex in a long-ass time... STFU, slap the lingerie on, and screw your man. I also think the lingerie was conversative, which from an outsider POV, looks like it would make sense... but knowing she enjoys lollipop sticks... whew.
She is giving me the ultimate "beauty fades, dumb is forever" vibes.
