How to Measure Your Hip SizeHow to measure your body

WUKA TIP: No tape measure? 
You can measure yourself with a belt or dressing gown cord and a 30cm ruler! Tie the belt around your hips, place a piece of tape or pinch where it reaches, then lay flat and carefully use the ruler to measure the length.

    Wish these had been around when I was younger!

    I purchased a set of these for different flow days for my daughter - she has given them 10/10! She said they make life simpler and way more comfortable - what more could you ask?

    I’ve had my WUKA’s for a few months now. I find them much much comfier than pads/tampons and you don’t have the worry of leaking or things moving around! I’m always scared of leaking after having a few mishaps but I can be more relaxed with these. They’re super soft too!

    These are fantastic!

    I don't normally leave reviews, yet here I am :)
    I wanted to tell you that if you have any doubts whether or not to invest in these period pants please don't hesitate!
    I bought my first pack of WUKA three medium flow pants and after just one day of using these I am absolutely sold!
    I will never, ever go back to wearing pads or using tampons again.
    These pants are so comfortable and so safe:)
    On my first day of period I went out for a two-hour long walk. Normally I would worry, you know what I mean, and I would probably want to go back home after one hour to check if "everything is ok" , however with these pants, I didn't worry for a second! It literally felt like I'm wearing normal underwear.
    Seriously best buy ever.
    AND I'm saving the Planet. Win win if you ask me:)
