Thick and soft.

It’s a win
Size: 5X, Color: Burgundy
I like this shirt. It’s super comfortable I bought 2 sizes to big in order for it to be super loose fit and longer. I bought the red/maroon color and it’s a very nice color. It’s light weight so you aren’t so hot that it stinks. The size seems to be true to size really. It looks super good with a nice pair of leggings. Seems well made. Washes good. It’s a win

Lightweight sweater
Size: XX-Large, Color: Navy
This sweater is very soft and lightweight making it perfect for spring and fall. The colors are beautiful and match the posted images. I have bought several different colors because I like them so much. I have larger arms and the sleeves have plenty of room. They do not wrinkle easily and are holding up well with routine wear and washing. My husband accidentally washed my navy one in hot water and put it in the dryer which made it fade and shrink considerably so be careful to read the label on how to wash and dry the garment and it will be just fine:

Very nice, yet hangs
Size: XX-Large, Color: Ivory
Soft, pretty and cozy. The bright clean color of white is crisp and pure.
Unfortunately, the shoulders are too big and it hangs or is too wide and in turn, the sleeves are too long.
The rest of it is proportionally correct for my body, so a different size would not work.

Lightweight & good price for quality
Size: Medium, Color: Camel Heather
Lightweight as other reviewers noted. I purchased camel color & oatmeal heather color for travelling on long plane ride while wearing with leggings. Ribbed cuffs and hem, which I like. V neck just right on me. Cotton blend knit, good. Color as expected. Sleeves long enough (yay!) Probably will pill eventually, but I'm not worried about it at the moment. Doesn't look cheap, which is nice for inexpensive top. I don't wear leggings a lot, so I don't think these will get lots of use, so until they start looking pilly I'll use them when I need to. I'm 5'7" & weigh 115 lbs, 34 A, and 37 hip. Size small in both colors draped perfectly, looser fit style, not clingy or tight around the bum, which is what I wanted. It doesn't look baggy or boxy on me, but I'm relatively slim so it may not fit as I've described for those with bigger bustline and/or waistline measurements and/or tummy. I think it is flattering on me, so I'm keeping them. I would say the size S it runs slightly big for my body type if that helps. Everyone is different even when we wear the same size! After reading reviews I purchased S and M sizes. I returned the mediums as they'd be way to baggy on me and too big across the shoulders.
