Inge, nice choices, and I would love a lot of them for under a simple blazer for a work look.
But then there are times when you just need a plain/simple tee for layering.
Sometimes it's because the outer layer is more elaborate and needs to take center stage, and sometimes in winter I wear a plain long-sleeved scoopneck under things as my cold-weather version of a camisole.
Of course, I'm always on Team Plain and Simple or whatever that team is called! I'm afraid a black layering tee is practically part of my "uniform". Now I'm trying to branch out a little...
Sveta, I'd love to see those merino ones! I'm not a Costco member, but sometimes have a chance to go with my daughter. What is the neckline?
