Truly comfortable organic underwear for femmes, for mascs, for every body - made ethically in Castle Simple!

I made Wonderpants for the simplest of reasons - I just couldn’t find underpants that fitted well and were comfortable. So I started making underpants from quality organic cotton with lycra that embraced and enhanced the curves and contours of the body, held their shape and were made to last. Try a pair of Wonderpants, they are so wonderfully comfortable

It’s officially singlet weather! Cold mornings, sunny days, layers to keep everything warm and secure. Like a security blanket against these changeable trans-seasonal days.

Wonderpants singlets are made from the same thick organic cotton and merino as our un**es. Cushy, supportive, generous length and every piece made by hand with intention and care in our Castlemaine workroom. It’s may seem like a lot of money for one singlet but once you feel the Wonderpants difference you’ll never go back.

Next in our new style range is The Wide Strap Singlet. ⁠
⁠
With contrast binding and a slight racer back, this style is so right in so many situations. The perfect yoga top. The perfect Pilates top. The perfect pajama top. Feels like your favourite un**es, looks like you care. It’s time for those shoulders to shine baby.

The Bound Leg High Top has the same waist height you know and love from The High Top but made with a bound leg band which sits a little higher and looser around the leg. Full bum coverage or pull them up for a cheeky fit.
⁠
Still made entirely from the same fabric (no elastic, no part tight or uncomfortable), the bands around the waist allow for comfort and ease, whilst maintaining stability and security. The leg binding is made from the same organic cotton.
