My 90yr old grandmother would like to wear a nice formal pantsuit to my wedding later this year. I’ve found some online at stores like the attached photo but have been struggling to find any like this in store as I know she’d like to try on before we buy. Any recommendations for stores that carry a larger selection of pantsuits like this? Willing to travel for it so any Chicagoland suggestion is welcome!

I'm open to renting or buying.

My nephew is getting married next year and this is the first grandkid wedding my mom is able to attend. She's in her early 80's and wants to wear pants to hide her legs (scarred from a car accident years ago) but also doesn't want to look casual or too old. (She's in her early 80's but only retired from nursing 4 years ago and walks miles every day...not your typical 80-something.) We've looked a little online (Amazon, David's Bridal & Eileen Fisher) but they are all grays or pastel colors...which she doesn't want. Any other places that sell either a formal pants suit or formal separates? Thanks!
