These have just arrived in the UK (Friday) after placing my order on Monday, such quick delivery! And under the limit for customs fees was an extra bonus. Just put them on and they are the comfiest denim!... I went for a size L (usually UK 14 in jeans) I'm 18 weeks pregnant and there's plenty of room to grow- they are definitely on the bigger side but just makes them even comfier and I don't mind the relaxed look! Could have probably got away with an M though, no regrets. Waiting patiently for my toddler to wake up from her nap to put her in for a quick carry! First impressions= Fab... likely to buy a second pair very soon 😂.KKay I.2023-12-09

I now have two pair of mumsies and I am totally in love. I wish I had them for my first kiddo. I have this paid and the vintage classic. I ended up going with a small in these and a medium in the others and they fit similarly. The sizing suggestions are spot on.

I love it. This shortie mumsie is SO comfortable, much more than any pair of jeans that I own. The buttons that unbutton for extra room are made for pregnancy, but babe, they’re also made for BLOATING days. They’re so customizable, I feel like they live WITH me. Perfect summer carrier or outfit, they look super cute.

Absolutely love the idea and execution of these overalls. My bubba loves to look around when we go out and doesn’t care for the pram so this is such a practical product. I’ve had numerous compliments on them, and would definitely recommend them to all mummas.

love these so much!! They are my go to outfit for errands because I can just pop baby in there and it’s so convenient. My only complaints are that they are really baggy on the ends and I expected them to be a more tapered fit, and I wish the top could tighten more to hold baby closer and make it hug my chest more when I’m not wearing baby. But they are so minor I kept it at 5 stars cause I wear them at least once a week. I love these so much and everyone needs one imo.

I am loving these coveralls. They are great for carrying my baby while I have two hands free for my older two and she loves being close for a cuddle too. 10/10 from me. Also the amazing mumsie time I'd give them an A+ for the best customer service. Thanks so much, I will be definitely buying another pair. x
