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:
