Anyway, I bought this top at the Collection store event organized by Summerilla two weeks ago as it was the only new arrival that was already on the selling floor that night and it was on my wishlist. I bought the shadow color in XS without trying it on, as I didn't have the time to try on but didn't want to miss the opportunity to buy it with the 20% off that they were offering for purchases made during the event.
As far as I can remember it is the first time that an item sized XS-L comes in petite sizes and that should have been a warning sign. The (regular) XS was HUGE on me (I didn't even take pics because it was so low cut that it was indecent) so I reorder in a Petite S (they honored the price).
After trying it at home I also changed my mind on the color because the pretty embroidery was a little bit lost in the shadow color (it was overall very dark).
This is the petite S in pale lilac:

Because it is shorter than the regular size but still big (especially around the armpits), it gets boxy:


It is very sheer and still low cut (although not as low as the XS that almost uncovered my umbilicus), so I would say that unless you are going to wear it all the time with a cami and/or a cardigan, it is not meant to be worn in the city. It is a bummer because I loved the color (the embroidery is in the same color than my crystal buttons, aka bling, cardigan):

But I really don't need something that I can only wear on an island (I hate wearing camis), so back it went. Sizing further down wouldn't have worked anyway because of the boxiness. I would say that this top will work better on tall gals with a long torso who can get away with their regular size. If you are a shorty, definitively order a petite in this top.
Summerilla, who also bought this top that night and as you know is much taller than me, looks great in it in this post.
Have you ordered or considered this top?
