Baby girls dresses

So my grandma was living in the Middle East for a while and brought home a bunch of beautiful fancy dresses for my baby girl. They are so gorgeous but I’m running out of occasions for her to wear them. She wore one for a photo shoot and birthday party, and another for Christmas. She has a really pretty gold and white one I was going to put her in for New Years but she was in such a tanks mood that I didn’t want to bother her even more so we just left her comfy clothes on. I’m totally regretting not putting her in it now as it was the perfect New Years dress and likely won’t fit her again next year. Does anyone have any suggestions on other occasions I could dress her up for? I’d love to see her get a bit of wear out of each dress at least. She has about 6. She’s almost 6 months old but tiny for her age, she’s still wearing 0-3 month clothes so I’m hoping these dresses will fit longer.
