Specific Bodyline Dress question...

I'm thinking of getting Bodyline's L442, and I have a question about the measurements. My upper arms are 10.5 inches/27 cm around, and when I've tried on a few Bodyline items in the past I haven't been able to get my arm through the sleeves. If anyone owns one of these dresses, could you measure the arm holes at the cuffs and let me know the circumfrence? I would like to know if I'm going to be able to fit before I purchase it.
Thank you!
