1. I bought the peplum shirt in both colors and in PXS and PS. The stripes are much less pronounced in the burgundy. The shirt is not as stiff as it appears because it is a blend of rayon and cotton with a small amount of polyester. The PS was slightly big through the shoulders which is typical for me. The navy PXS was a little small through the shoulders, and the burgundy PXS was perfect. The size difference in the two colorways was minor.
2. The Chill Pill cardigan is fun but for a taller person; this doesn't come in Petite. It is cut quite generously so a person could go down a minimum of one size. I did, and it was still very large.
3. I ordered the poncho sweatshirt in the charcoal and in two sizes. The smaller of my two sizes is plenty generous. The question is whether I *need* this.
4. The Mystere sports bra runs VERY small in the cups. As in two sizes smaller than advertised.
5. The Moving Comfort Fiona is quite different from my four other bras in the same style and is not as robust. The band runs much bigger, probably true to size which means it is too big for me.
6. Zella bomber is yucky sports fabric and cut narrowly. I was not impressed.
7. Caslon drapey sweatshirt jacket. I decided that super casual drape really isn't my style and that I would prefer charcoal -- which is not an offered colorway. Otherwise, this is nice and the cuffs are finished such that you can roll them.
8. Pleather vest: This is very heavy and textured. The bottom band flares out a bit so it looked dumb on me since I am 5' 1" and this is a regular size. The hardware on this is rose tone which one rarely sees. I would recommend this for a regular height person.

9. Zella vest: This is VERY nice. It is a bit long on me, but that's to be expected since it's a regular size. It fits very close to the body and is pretty warm. I don't normally spend very much for gear so I will probably return it and continue to wear the fleece vest I picked up at REI.
