I'm 5"3 and 115 lbs and 34 b bust. Would the small be a good fit? Online it says that it measures 38 around the bust on a small, but everyone says that they run small:(. I'm pretty confused. Should I go for a small or an xsmall?
I would recommend going with a small. You'd probably like a little bit of room in the jacket, especially if you plan on wearing a sweater or other layers underneath.
I have almost the exact same measurements as you, i believe i'm about 109 lbs, and i tried a small on and it was perfect! so i would go for the small definately, and i tried it on with a hoodie underneath and it fit the best even with it!
I'm almost 5'5 and 118 pounds. I just bought a Women's CG Chilliwack Parka in Brown - size S. I bought the jacket for function not fashion and the size S doesn't ride up my back, which the Chilliwack is known for, and I have lots of room in the sleeves to pull the cuff over my mitts.
Where it is big is through the body and chest, easily 4-6 inchs of overlap. If you want a tight, city jacket and don't mind it sitting high on the waist I would recommend the XS. if you are looking for a jacket to wear while doing winter sports, to feel warm and cozy on those extremely cold winter days go for the S.
NOTE: I haven't tried on the XS to compare it to my S.
