Absolutely. I am so sentimental, and particularly about clothes as they relate to memories, and to my mom especially since her passing.
In fact, last summer I posted a new dress that I couldn't resist buying. Even though I didn't "need" a dress, it appealed to me not only because it fit and flattered me so well, but it was a beautiful floral print on a black background, and the floral reminded me of my mom. I will occasionally be out shopping and see a print that makes me smile because it looks like something she would have loved. She adored prints!
I also have a small stash of sentimental clothing items that belonged to my mom, my dad, my grandmother, and even my great-uncle (my grandparents passed away before I was born, so he was the closest I had to a grandparent). I have even kept a couple of sentimental items I wore when I was younger, but I'm gradually becoming more selective about what I hold onto.
As for newer things, I enjoy seeing items out in the stores that remind me of styles from my childhood or young adulthood, but I will ONLY buy them if they fit into my life and my style now.
