Stripe Envelope Neck Knit Top

Wanted to share sizing/fit info for everyone who, like me, struggles to get the right size online. I'm a 36D-29-38 and decided to size down to Small because I prefer a tailored fit. The chest area fits perfectly (loose fit around torso), but the sleeves feel just a bit tight -- I get some resistance if I try to move my arms forward. I'm going to keep the Small as I got the fit I wanted, but a Medium would be safer if you're worried about any tightness.

I originally bought this top in the blue stripe print. Although I am not a fan of stripes, I decided to keep it because it fit really well and is cotton. I then ordered the same style in the coral and white. Both of these tops are transparent. I do not appreciate such thin fabric and plan to return. I simply do not understand why they have cheapened t shirts to such a degree. Its a few cents more for a better quality fabric. I am disgusted that I have not been able too find a decent white t shirt in years.
