Diane Von Furstenberg Paz Cotton Sheer Ivory Wrap-over top in size Small which she translates as a UK8. It always helps if familiar with the brand and her sizing. The measurements flat to fully stretched are 34"-38"bust, 28"-36" waist, 22"length and 28"sleeves. The loose crossover front is typical of DVF's dresses, almost ballerina style, finished with a ribbed hemline so lies nicely above the hips, blouson style. Deep V-neck, long sleeves, ribbed cuffs, loose fitting, terribly soft and very lightweight, it fits true to size. This can dress up a pair of jeans or be worn with a straight skirt, whichever you chose it needs very little to make it the star of the show. It is very sheer so would need to adjust undergarment choice accordingly but be aware your skin would be visible throughout.  New with tag (a little torn), but there is a hard-to-see pin prick pull on the left sleeve and one on the seam by the ribcage. There is very faint mark possibly due to storage on the front left side as well-see photos.
Diane Von Furstenberg designs such feminine pieces and this is a perfect example.
