Nothing super exciting but fits the classic trend, I wore rtr boyfriend shirt with rtr jeans, super fresh!
Overall Fit
Just right

Great look and quality. If you’re looking for a more fitted look, size down. I have long arms and these were plenty long enough.

Wide v neck that sits awkward on the shoulder. Simple sweater perfect for casual wear

I wore this so many times, it goes with anything and looks great over shorts, work pants, leggings or dresses. I tossed it in my bag and wore it all over town

Wrote it traveling, on a date and then generally out and about. Adorable slightly oversized sweater, great for layering in transitional weather. Might buy it.

I'm docking a star because the cream is a little on the yellow side and so it washed me out. Cute casual vibes, not very elevated and the knit is a little starchy.

I wore this on a flight and it was cooler than expected at my destination so I wore this nearly daily for 5 days! Good thing I didn't spill anything. Oversized fit, thick cotton. Low V but worked for me.
I ordered a large knowing it is oversized. I was swimming in this. Could have gone medium.
Very big but great casual sweater you should size down at least one and maybe two sizes, even for an oversize look!

Oversized sweater that did not wow me. Loved that it was 100% cotton, but I didn't find it flattering.

this is an oversized boxy fit, and looks very sloppy on
