Please feel free to get in touch via the contact page or DM me on Instagram @mamabossshop to check if your size is in stock before your order if you wish :)

Due to offering an extensive colour and size range, I'm unable to keep all sizes in stock. I place orders for clothing twice a week to keep any additional shipping fees low. Should I not have your size in stock I will need to order it and this may add additional time to when your item is sent. So as an average, I state that items may take up to 4 weeks.

Sizing: Generous Fit

These are a classic fit t-shirt, like a band tee! Sizing is somewhat generous and runs slightly larger than a standard shirt so please bare that in mind when thinking about the type of fit you want this tee to have, as well as using the suggested size guide below.

As a reference, I'm a size UK26-28 and wear a 3xl like a regular fit tee, It doesn't cling to my curves, but also doesn't feel like I'm wearing a tent.

Size Guide - Chest measurements:
S - 34/36" (UK Size 8-10)
M - 38/40"( UK Size 12-14)
L - 42/44" (UK Size 14-16)
XL - 46/48" (UK Size 16-18)
2XL - 50/52" (UK Size 20 - 22)
3XL - 54/56" (UK Size 24-26)
4XL - 58/60" (UK Size 28-30)
5XL - 62/64" (UK Size 30-32)

Sizing: Generous Fit

These are quality sweatshirts that wash so well! Soft and cosy on the inside, making this your number 1 go to jumper!
sizing is somewhat generous and does run slightly larger than the stardard size, so please get your size if you it to simply just fit nicely, for that everyday wear, however if you want it baggy and have some extra room, then size up.

As a reference, I'm a UK26-28 and whilst I can fit into a 3XL, I like to have a bit more breathing space, so I opt for a 4XL.

Size Guide - Chest Measurements:
S - 34/36" (UK Size 8-10)
M - 38/40"( UK Size 12-14)
L - 42/44" (UK Size 14-16)
XL - 46/48" (UK Size 16-18)
2XL - 50/52" (UK Size 20 - 22)
3XL - 54/56" (UK Size 24-26)
4XL - 58/60" (UK Size 28-30)
5XL - 62/64" (UK Size 30-32)

F**king amazing tee!!

This tee really hit a note with me when Lucie first released it. Mum guilt is that niggling feeling that lives rent in your brain, it's time to tell it to get out. T-Shirt is perfect, unisex sizing means it's comfy -basically I live in this tee at weekends

My new favourite tshirt!

Love this tshirt! I got it in white with black writing/image in a medium (I'm a size 12 on top) and it's so lovely and soft. I like my tees baggy so this is ideal as I can tick it in, wear it out or put a knot in it. It's long enough to wear with legging as well which I love!
This was my first purchase but definitely won't be my last.


I won’t lie I’m in SHOCK. I ordered two tees one of me and my LO and for the price I was very much expecting the standard print tee...but NOPE. It’s sooooo soft and fits amazingly!! Honestly as good as ones I buy for £30+ I can’t wait to order more. Service was incredible (I was alittle indecisive). Couldn’t recommend enough. As a 2xl size lady I love the fit and that the sizes go up / accommodate for everyone. ✌🏻

In love 😍

I am insansly fussy about clothes, sizing, seems, fabric you name it BUT i risked this T and im so pleased i did. Sizing is 100% true and the quality of is amazing. And its heavy so its actually hangs down. Cant wait to buy more 🙌
