UK size 8 (US size 4/small). New with tags only tried on once, never worn. The fabric is super lightweight and soft with some mesh fabric throughout so it’s partially see through. It is cinched slightly in the waist so it hugs curves quite nicely! The fabric has some stretch to it but it definitely is on the tighter side. True to size, I usually wear a medium but I definitely overestimated how stretchy the fabric would be so that’s why it didn’t fit me exactly how I anticipated.
