Months ago, I identified a need for knitted staples in my wardrobe because the length and material of my current tops don't mesh with the humidity or my lower-rise bottoms. I don't have many tops--fewer than 10 are in circulation--but I am very particular about what I want.

Specifically, I'm seeking all of these characteristics:
*Thin material with some stretch
*Boatneck/ballerina neckline in the front, ballerina in the back
*Short to elbow-length sleeves

Years ago, I had purchased an elbow-length sleeved ballerina top from J. Crew, but the fabric was too thick, and the cotton stretched out too easily. I noticed that Theory has a few tops that seem exactly what I'm looking for, but at $150 a pop, I'm expecting it to come with a free pair of trousers.

So, my question: do Theory knits hold up well to the wears and tears of daily life? Will they pill or retain sweat easily?

If you know of any tops that match the description above exactly, please share.
