About Midies
What makes Midies different?
We design underwear that solves real problems — chafing, digging, sweating, layering. Everything we make starts with our custom made fabrics that focus on stretch, softness, breathability and quality.
Where are you based?
We’re Australian-owned, shipping locally and to New Zealand from our Brisbane warehouse.
Are Midies sustainable?
Yep. We use oeko-tex® certified fabrics only and compostable garment packaging.
Fit & Sizing
How do I choose between the 5″ and 7″?
The 5″ is your everyday coverage — smooth under shorter hemlines. The 7″ gives full-length confidence and zero thigh chafe - perfect if you're taller or thicker in the thigh.
Do they roll or dig in?
Our smooth-fit waistband sits softly on the waist and while offering moderate support will not dig in. The leg hems are wide and made using a special stretch thread to eliminate any digging. Finding the correct size and length for your body helps to eliminate rolling and riding up.
Are they true to size?
We believe so. We know many women size up when it comes to undergarments - to eliminate digging in and tight waistbands. However we're different. If you’re between sizes we recommend sizing down. Our fabrics are stretchy, designed for you to move freely.
Fabric & Care
Why bamboo?
Because it breathes, it’s soft, cool, moisture-wicking, and gentle on sensitive skin — no static cling, no synthetic stickiness.
Are they see-through?
Never. Our bamboo fabric is thick enough to stay opaque, even in lighter tones. Our custom bamboo is 250gsm.
How should i wash them?
Cold wash, line dry, skip the fabric softener. Treat them kindly and they’ll stay like new for ages.
Flow — Period & Light Leak Protection
What’s flow?
Flow is our leak-proof underwear that looks and feels just like your favourite smooth-fit pair — soft, breathable, and smooth under clothing.
Do they feel bulky?
Flow absorbs up to 15ml (about 3 tampons) without that heavy or padded feel. There are no bulky seams around the inner thigh or under gusset. The Back remains seam free.
Do they smell or trap heat?
No. The outer garment is made from our bamboo which keeps things fresh and cool. The gusset liner is a graphene based fabric designed to eliminate bacteria, which also controls odour.
How should I wash period underwear?
Pre-rinse before machine washing. A simple way to do this, take them to the shower with you and rinse them there - no mess, no wasted water.
Orders, Shipping & Returns
What if my size isn’t right?
You can use our try-on guarantee to purchase a size or style that fits better. No need to return your first open pair. Any unopened pairs can be returned for credit or refund.
How long will my order take?
We dispatch quickly (next business day) from Australia — most local orders arrive within a few days, NZ takes a little longer, typically 7-10 days.
Do you offer free shipping?
Yes, on orders over our free shipping threshold $90 within Australia.
