MOB Dress Question...inspired by Kelley's MOB/G dilemma lol

My mom REFUSES to have a typical MOB dress. Wants nothing to do with anything that involves a jacket thing. However, she does want something with 3/4 sleeves because end of Sept the weather could go eith way. She wants me to look at BM dresses that come in 3/4 sleeves........has anyone seen any really nice BM dresses with sleeves like that? The only ones I've seen are for 'modest BM's'...and aside from the sleeves, my mom doesnt wanna be completely covered up

any suggestions/ideas??

TIA
