I've been needing to buy some new blazers for work for quite a while, but I kept putting it off because we're TTC and I didn't want to end up with brand-new blazers that didn't fit. But, there's not holding out any longer, and last night I ordered a bunch online in two sizes - my current size, and the next size larger.

Did your arms grow during pregnancy to the point that blazers were too tight? If so, should I hold on to a few blazers in the next size up, or just buy one or two in my current size, and then buy maternity blazers when I'm pregnant?
