Where to look in person for engagement photo dresses (Toronto)

Hi all -

I have engagement photos next month and we're taking them downtown. Because of this, I want something a bit fancier (midi length, more structured material) versus a traditional casual white dress.

My mom is coming to town soon so we can look in person but I'm stuck on where to go! Right now the only places I can think of are Park & Fifth and Ever New. We have already done Aritzia when I was home (found some options if I can't find better).

Any other suggestions? I don't mind buying a dress vs renting since I plan to wear it again for the bridal shower or rehearsal dinner.

Thanks!
