I ordered a medium I am 5'5 155lbs slim thick build with a butt. Beautiful colour and design however, the top was larger (i am 32ddd) and the bottom was true to size (M).

it’s a really cute outfit the problem is it runs big I’m a 2x I purchased a 3x just in case the arms were tight but honestly I wish I would’ve done a 2x basically just stick to your original size because the bust area runs large and the skirt will fit but if you want it to be fitted to your body just order your original size so it’s not just sitting on your body but actually forming to your shape
