Marley -- no I didn't try a size up, I should have! The fabric is like a clingy blouse material, to be honest. Whenever I have blouses like that, where the fabric clings to my bust, tummy and butt, they turn into orphans. Even when made out of silk. I live in an area with very low humidity, year round (except when it rains) so static is part of my life.
I was hoping these were a thicker fabric. If they were a better viscose, rayon or tencel they would be perfect.
This has been a learning exercise, fabric matters so much and I will avoid clingy polys and silks for any type of clothing (even a scarf) from now on.
CinnamonFern -- I know they are terrible and I feel I deserve some credit for posting some really unflattering pictures on the internet! LOL!
Tina -- I love your suggestion of keeping both sweatshirts! I love the architectural nature of the first one and like the way it looks with skinnies. The second one is a less edgy silhouette. Both garments but especially the first one, are of good quality. In fact the first one is comparable in quality to a Marc by Marc Jacobs fashion sweatshirt I also got in SF, yet was a fraction of the price.
Zara is still fairly hit or miss!
