Blouse - I’m wearing a size 4. It’s on the larger Size so id go a size down. This blouse has a tie at the back that pulls the waist in so it would also look really nice with jeans. Skirt - I’m wearing a size 4 and fits perfectly around my waist. I’m usually a size 6 so it’s slightly oversized. I wish they also did it in petite as the length is a little long on me. I’m 152cm so I’m super short, so this would be an ideal length for anyone over 5ft. corporate businesswear officewear
