I recently started the game. I enjoy it and love seeing my store build and grow

All I have figured out so far is have to have 2 clothes and racks per row like below. It gives more clothing and they walk around the rows.

____________ <clothes/racks
____________

____________
____________

I also figured that you can put $500 gold mirror on the walls, space to walk then have dressing room. For me I dont like that it can block my view to potential areas I can place clothing and save money on mirrors.

Mirrors on wall > __ O__ O__O ___
Space to walk
Dressing room > D D D

everything depends on your liking. What have you found out?

Also, Ive seen some shops have lets say 5x5 area of stacked clothes. What are they trying to do?
