I'm 5' 9" and 152 pounds, so I'm in your zone. My stats are 37 bust, 31 waist and 38 hips.
I always reckoned I looked kind of wimpey as a man but I'm better in a dress.
UK sizes are a little different - I can wear a size 12 dress in most brands though some are a little too snug and I have to go up to 14. Definitely size 12 for skirts.
