Amazing people and perfect for what I needed
Great experience with Mama Rentals! Had a question about sizing and they measured the garment stretched for me in a timely fashion so I could compare to myself. Ended up getting a size small (which was 96cm measured around waist stretched) as my waist measurement when pregnant was 85cm. The dress fit, but was quite fitted around bust and underbust at my waist, and I would've preferred it to be a bit more flowy - so next time I'd rent a size medium. Could not fault their service and the quality of the garment! Despite it not quite fitting as I'd preferably like, it still fit beautifully and my photos turned out gorgeous.
Hi Rebecca,
First of all thank you so much for your lovely review and the beautiful photos, you look so stunning! I am so glad you loved the Coven & Co Posie Gown. I'm however, sorry to hear that the dress was a bit too fitted in certain areas and did not quite fit the way you had hoped. We understand that finding the perfect fit can be a challenge, especially during pregnancy, and we appreciate your patience and understanding as you navigate this process. We are glad that despite the fit not being exactly what you had in mind, the dress still looked beautiful in your photos.
We really appreciate your feedback on the sizing and fit of the dress, as this information can be helpful to other customers when selecting their sizes.
Please feel free to share some of your other photos with us when you have them available, let us know as well the social handle of your photographer so we can tag them as well:)
I hope to be of service again in the future when you need a beautiful gown for your newborn or family photos, as you probably know already they are all suitable for non-maternity too! Thank you again, Alice xx
