You've done great on that overall look. I really love all the framing over the entrance and the bay windows and tower sections!
Benches, flowers, and a walkway will complete the look for the outside with maybe a fountain or sculpture.
Inside you could have maybe a ladies floor and a men's floor like some department stores have, or a tatoo parlor (and stylist sections) upstairs with clothes racks on the ground floor. The top floor could be where the stylist works on research ideas at the drafting table with a couple of the dress models.
Each floor could have a bathroom or two. I like to use the all-in-ones for toilet stalls and add sinks and mirrors for appearances. (This cuts down on stinky sims as they get a shower when they use the toilet.) I also like to add potty chairs and trash cans just in case I have toddlers visiting.
If you have a lot of room, you might make a children's play area to entertain small ones while mom shops.
And, you could add places to sit for the long-suffering husband or worn-out mom as you know how some spend so much longer looking and trying on everything than others. Add a book rack and/or television to give them something to keep them occupied.
Do any of those ideas help?
