Your navy mini looks so beautiful and sexy! Which season is it from? Love a deep dark navy! Sounds like you got a nice price for the black mini square. Do you have a bigger classic flap in black? If you do then perhaps you could even just let the square go without replacing it with the rectangular, if that makes your collection more pleasing to the eyes on the shelf? I have a suggestion - try replacing the square mini with a so black rectangular. I have one and could imagine it fitting so perfectly with the rest of your minis without making the navy look redundant. The navy definitely deserves to stand out

Congrats on getting a new wardrobe and I guess once it’s up you will eventually realise what decision truly makes your heart sing!
Your pictures of this bag have been looking stunning so far! I’m not into grays but your pictures certainly make me want to check this bag out in person before deciding! It’s like there’s an aura to it!
