So I've recently lost a bunch of weight and am a Medium now. This looked big still in the store, so I sized down to a Small. I just tried it on and could legit use an XS or maybe even an XXS. It's THAT big. Consider it a solid 2 sizes off, possibly 3 when ordering. It's a fantastic quality and really pretty.

I love the higher v neck that gives room at the neck but doesn't strangle and isn't too low. The fabric is very soft and washes well. Great everyday tee. Note these have a VERY relaxed fit I would suggest ordering at least one size smaller than usual.....it is still loose fit for me.
