Rapunzel earrings
Style: June - Alexandrite
I got these earrings as a gift because we were going to Disney and I wanted to dress up like Rapunzel and these were perfect for the look. They are also small and comfortable.

Cute but Wrong Color
Style: July - Ruby
These earrings are really dainty and pretty, and my daughter loved the style. Unfortunately, the color wasn’t quite right for her birthstone—her ruby birthstone is a deeper red, but these leaned more toward red-orange. They still look nice and could work for other occasions, but we were a bit disappointed since we were hoping for a true ruby match.

Love this bra!!!
Color: Light Beige, Size: 42D
This bra is amazing. The fit is perfect and it works really well as a minimizer. It doesn’t poke, stab, or leave any indentations or marks around my breasts or back, which is usually a problem for me with underwire bras. The wire also doesn’t dig into my skin or stomach at all.
It’s incredibly comfortable and provides great support and lift. My breasts feel secure and well-supported all day. I highly recommend this bra!
