Review: Superb - Great quality, fit and price
Review: Perfect - Amazing! I wasn’t sure which length to go for as I’m 5ft 9 and I wasn’t sure which size as I’m obese but carry my weight all over and I want to wear clothes underneath. I ordered the navy in XL. The quality was fabulous. The poppers are good and the elastic waist is nice. The length is perfect for me, maybe a smidge too long but ideal for tucking in boots. The size is perfect - I am size 16 in women’s and the XL allows me to wear thick jumper and joggers underneath and have room for movement. I’ll buy some more for the rest of my team

### ⭐⭐⭐⭐ Clothing you need for work.
*by B***A on 11 September 2025*

Just the clothing I need when I am doing my decorating and DIY work. They are eay to use and very durable with good wearabiliy. And I washed mine to soften the overalls and any excess die. So in the future I won't run the risk of accidentally die any other items of clothing when I put them into be washed. Love the metal press button clips much better than a plastic zip. My overall conclusion lovely and I ordered 5xl, plenty of room to move around in.
