The story

Thanks for stopping by my shop! My name is Alyssia, and I'm the creator and one-woman show behind Rosie Sunday.

I started Rosie Sunday on Etsy in 2022 as a way to supplement my income while on maternity leave with my daughter, Rosie (the namesake and heart behind this little business). What began as a way to add a bit cushion to our family budget quickly became a creative passion project when I realized how much I loved designing personalized, meaningful gifts centered around mothers and the people they love most.

One of my first and still best-selling products is the Birth Month Flower sweatshirt. Each design features the birth months of the important people in your life, a wearable reminder of the relationships that shape us. My own sweater represents four generations of women in my family: my grandma (January), my mom (April), myself (June), and Rosie (September). Knowing that I get to create something equally personal and sentimental for my customers is one of my favourite parts of this business.

Every item is designed by me and made-to-order by our production partner with intention, care, and a genuine love for celebrating the people who matter most. I’m so grateful you’re here, and I can’t wait to create something special just for you.

I get so many compliments on this sweatshirt! I did my three daughter’s birth flowers on the dark green sweatshirt. I ultimately went for green because I have green eyes but the heathered grey is gorgeous and I may get another item in the future! The sweatshirt is super soft and I want to wear it everyday. Love love love!5/5 5/5 stars

This is a gift for one of my closest friend’s birthdays. I think it is a meaningful and practical present. I’m quite sure she will love it and will wear it often (with pride) as Fall and Winter are approaching. The sweatshirt material is thick and soft and the colors of the flowers are so pretty! I am happy with my purchase. The seller is responsive to questions and happy to help in whatever way she can. Thank you!5/5 5/5 stars
