The everyday one.
Ella is a classic brief — mid-rise, full coverage, finished with a tulle waistband that lifts it out of the basics drawer. Simple, and quietly pretty.
It holds 30 ml, the equivalent of 3 tampons, which covers a medium flow through a full day. If your flow is heavier, Ella is the style you switch to at the end of your period when things settle.
The absorbent panel is unusually wide across the back, so it's a good choice for sleeping — you stay dry whichever way you turn.
Available in sizes XXS to 3XL. Our model wears a size S.
Rinse in cold water right after wearing — cold water first, always.
Machine wash at 86°F (30°C) with the rest of your laundry. No fabric softener.
Air dry. Never tumble dry.

This is my first time buying period underwear… and I am delighted. I got to test them through my current cycle and they're unbelievably comfortable. I felt good in my body for the first time in a long while! The designs are lovely, the finishing is excellent, and you genuinely feel pretty in them. I chose Loulou for their transparency and their environmental commitments, and I'll be buying another set in the next few weeks. Don't hesitate, go for it!
I took the plunge after months of hesitating — and I've just reordered! Really pleasant to wear, good support, no damp feeling and no leaks despite a heavy period.
Very happy with my order! I haven't tested it yet but I already own several from this brand, so I have no real doubts about how well it works. It's very pretty, I took my usual size and it fits perfectly.
Feminine and comfortable at the same time. I really recommend it.
Excellent quality and no leaks. Perfect!
Perfect, really pleasant to wear. The high waist fits true to size.
Really pleasant to wear and no leaks.
Runs a little small (you can see the seam lines), but perfect for overnight!
