Crew stripe sheath fitted very well until i turned around. the waist section, where the stripes wrap around the waist had extra fabric and didn't lay well. i am 5'4", 120 lbs, 32c, 26" waist, and 32" hip usually wear a 0 or extra small in the maeve clothing that isn't a fitted style. i bought the s, which fit well except for the waist issue described above. this is a fitted dress. i hope this is just an issue with the dress i received. it is a great style idea.
