Hi y'all. I have found this site immensely helpful in figuring out fit and style and was hoping you might be able to offer some advice to my mom. She is in her fifties and trying to enter a different field of work (long time coming) and it will require a more business casual wardrobe. She is trying to get a few workhorses for interviews and then build up the rest of the wardrobe later. The hunt is currently on for tops that will work for spring/summer when it eventually warms up. Any advice would be appreciated.

Particulars:
Pear shaped, XL on top ( not really in plus size, the worst in between zone)
Proportions are on the petite side for tops.
Sleeves of some sort are a must, preferably at least elbow length or a little shorter.
Stylistically something more conservative but also something that would give her confidence walking into an interview.

Lastly, we are in Canada and international shipping is the worst so any suggestions for brands or stores in Canada would be great.
