Short answer: Yeah. Especially if it's a black or other soul-sucking color turtleneck.
Long answer: it depends on the turtleneck! As we all know, since I complain endlessly about it, I'm short, all over. Including my neck. And the vast majority of turtlenecks (99.9%) are scaled for taller people with longer necks. Not even talking giraffe necks... I'm just talking normal size necks... mine is proportionately short for a proportionately short person. So, flattery aside, the majority of turtlenecks annoy me to no end because there's just too much fabric and they .. well... ensconce my entire chin. LOL
Every now and then I can find a t-neck that is scaled just right, and even though I do have the whole saggy aging face thing going on, it works fine. There was a time in my life when I was on the "hunt" and I built up a collection. I have 4 t-necks that fit the bill. But then I stopped hunting - and also stopped wearing them. Because of problem #2... once I solved the neck issue, I realized they make me look too chesty.
That said, though I do think I look far better in a V or scoop neck, I've got aging skin on my chest too. Which now needs covering up. So, if it's not one thing.. darnit, it's another!!
Right now I'm playing around with crew necks that are cut lower than your usual crew neck. Low enough, they elongate the neck, but still high enough they cover the aging decollete. Seems this season there are more options in this area? Or is it just me?
