I was looking for a heavy, hardcore parka to wear over my suit (lawyer) that could be used for commuting to/from court and waiting for buses. I'm 5'4 125lbs, broad shoulders, long arms, 34D chest, short waisted and straight figured from waist down...waist : 26", hips: 35". I have problems with most women's jackets b/c they cut me at the underarms and through the chest. Generally, if I go up in size, the body is too wide.
In this jacket, I tried the men's small (usually wear that size) and it was way too big; women's medium (was slight tight through the chest and just fit in the body); women's large...perfect. Women's large gave me the extra room through the shoulders, chest and arms, but not too much through the body. Although I haven't tested, the coat out yet...the fabric is extremely durable and the hood is amazing. Your head/face fit into the hood like a deep pocket so, with the fur edging on the hood you're protected from the elements blowing around. Will give you an update with I really test it out.
