The bra looks great, it’s comfortable and gives good support. I’m a 34 D and I wear it comfortably to the gym for weight training and tread classes. I love the metal bar design in the middle - it looks great and doesn’t dig in or bother me at all during workouts.

The metal piece gets out of the fabric while your are putting it on, it took me forever to put it back inside.

Support and design! Impressed is an understatement. I was unsure how this would fit, but I am truly obsessed with the shape it gives!

Such a comfortable material. It goes well with all kinds of looks, well supported the body with regular sport attire.

Frequently asked questions
How does MICHI fit?
MICHI products are designed to fit true to size with a sculpted, body-contouring feel—supportive, never restrictive.
That said, our fit has more 3D shaping and is intentionally more tailored than mass activewear brands:
- Bras fit slightly more compact for a secure, lifted feel — if you’re between sizes, we recommend sizing up.
- Leggings may feel slightly more relaxed and comfortable through the body — if you’re between sizes, we recommend
sizing down.
- Jackets and hoodies have a modern, sculptural fit — if you’re between sizes, we recommend sizing down.
If you’re between sizes overall:
- Size up for a more relaxed feel
- Size down for a more compressive feel.
What is the exchange policy?
MICHI offers exchanges only, issued as store credit, for eligible unworn items with original hang tags attached within 30 days of delivery.
Refunds to the original payment method are not offered unless specifically approved by MICHI.
Please review our Exchanges & Store Credit Policy for complete details.
What activities are MICHI styles designed for?
Our pieces are designed for studio movement—Pilates, sculpt, strength—and elevated everyday wear beyond the workout.
Do your fabrics feel soft and compressive?
Yes. Our fabrics feel silky-soft and sculpting, with supportive compression - engineered for exceptional stretch and recovery to hold you in without restriction, allowing complete freedom of movement.
