Hmmm. How are you tying them? As a fellow round-faced C, I think that scarves are more slimming if you drape them around your neck and let both ends hang (i.e., no tying). Or, wrap them around your neck ONCE but make the loop loose, not snug, so it sits on your decolletage (where a necklace would be) rather than right up under your chin. That way they have strong vertical lines (like MSP is always talking about) and don't visually shorten your neck. Or, look up various ways to tie a scarf, and try them in front of the mirror so you can see which ways look better. If you do that, report back -- I'd love to know!
