Product Insights

The Miiyu Astra Wireless Push-Up Bra offers a dramatic push-up lift comparable to more expensive options like Leonisa, thanks to its molded cups and recycled nylon-blend microfibre that resists moisture and maintains shape with stretch recovery. At $39 CAD, it provides underwire-like support without irritation, with a seamless, invisible silhouette under tight tops. However, buyers must size up by 1–2 bands as it runs small, and may encounter quality issues such as scratchy seams or knotted threads; inspection and proper fit are essential to avoid discomfort from the narrow band or fixed padding.

Verified claims

Sizing
Band runs small; buyers recommend sizing up by 1–2 bands.
Support
Underwire loyalists confirm comparable support without irritation.
Value
At $39 CAD, provides more dramatic push-up lift than Leonisa at $81.
Quality
Buyers report occasional quality issues like scratchy back seams or knotted threads at the clasp.
Seamless visibility
Virtually invisible under tight or thin tops, with no visible lines.
Moisture
Recycled nylon resists moisture and dries quickly, preventing clamminess.
Stretch recovery
The 20% spandex provides stretch recovery to maintain the bra's shape over time.
Lift mechanism
Achieves a moderate push-up with a more dramatic lift than comparable under‑$40 wireless bras.
Invisible silhouette
Seamless, smooth cups stay invisible under tight or thin tops.
Strap adjustment
Adjustable straps are the only way to customize lift; padding is fixed.
Care
Hand-wash cold, no fabric softener, lay flat to dry.
Padding
Padding is non-removable, simplifying washing.
Initial inspection
Inspect for rough seams before first wear for comfort.
Design
Two-hook closure boosts durability; moulded cups deliver underwire-like support.
Finishing
Some buyers report finishing defects like knotted threads at the clasp.
Fabric
Recycled nylon-blend microfibre is soft, quick-drying, and retains shape over time.
Fit
Narrow elastic band can dig in and leave marks, especially if worn true to size.
Seamless and wireless
Wireless design with smooth seams and adjustable straps minimizes chafing and irritation.

Comfortable, right amount of push-up

Denise D.

This bra is very comfortable and provides a nice amount of push up.

Très confortable

Denise G.

Habituée des modèles avec armatures qui me donnent des allergies . Celui-ci même sans armature j’ai été surprise du soutien , légers coussinets juste ce qu’il faut pour une apparence naturelle . Coupe seyante . J’ai adoré pour le sport , se lave bien . Invisible sous les vêtements , J’en achèterai 2 autres

Fait très bien

Fits small

Lori B.

Seemed to fit small for my usual 34C after measuring my body and using formula from the sizing chart. I’m 131 lbs and 5’5”. The straps were the deal breaker, though. Rough on the edges and dug in very bad as they were too thin. Sad because the design of the band and cups seemed seamless and nice. Straps and cup size being too small ruined for me. Returned.

Très confortable

Fait bien

Sarah L.

Elle fait bien, pas d'armature, mais maintient une belle forme et reste en place. Par contre la mienne semble avoir un défaut, a la hauteur de l'attache, les fils sont plein de noeuds, donc frottent constamment sur la peau. J'ai dû les recouvrir

Mauvaise couture

Émilie M.

Les coutures du dos étaient coupantes. J'achète ce produit depuis plusieurs années, mais cette fois-ci, le produit n'était pas bien conçu.

Good quality but bad fit

Chantel B.

I wanted to love this bra because it looked similar to the ones I purchased several years ago at a store that are no longer available. The fit was very on the small side. I measure 31 inches below my bustling and normally take a C32. This bra was SO tight. I bought an extender but now the straps fit too far apart. Definitely a miss.

Bon achat

Annie C.

J'ai hésite puisqu'habituellement je préfère avec armatures, mais auccun regret. Bon soutien, et bonne qualité. Seul "reproche", mais c'est très personnel, c'est qu'il n'est pas disponible en 38A. J'ai donc dû prendre 36A, mais heureusement, il reste confortable.

Confortable et beau

Élyse-Anne P.

Soutien-gorge qui semble bien soutenir malgré l'absence darmatures. Confortable et juste pour la grandeur.

I like this bra, I

Anna F.

I like this bra, I initially bought it but had to return because although the cup size fits, the other measurements are much too small and tight. So for instance, if you are a size 32B, to fit you must purchase 36B.

Very comfortable

Jo-Ann F.

Gives me a great shape and looks good under clothing

Not true to size. Poor quality round loops for the straps. Give it away instead of paying return shipping.

Not for me

Stella F.

I really love Simons bras but this one disappoints. The fitting was a lil tighter although I ordered my exact size plus the shape was quite weird too. Maybe it can work for others but it’s not for me, I returned. (For reference it was a blind buy)

Déçue

Ne tient pas vraiment en place.

Best Bra

Sam L.

I have such a hard time finding bras, but this one is perfect! Nice and soft with not too much of a push up. Bought one in every colour.

Ultra comfortable

Ultra comfortable

Moyennement satisfaite

Valérie D.

L’élastique est trop étroit au contour et durant la journée il fait mal. Si je le mets plus serré, il coupe et fait un bourrelet.

Doux et confortable

Denise G.

Ceci est le 2e modèle que j’achète car trop confortable . J’ai toujours porté des modèles à arceaux . Ce modèle supporte autant et en plus ne blesse pas la peau comme certain modèles à arceaux . Cette couleur est très belle . Le mauve uni est aussi joli

Great Bra

Sam M.

I have been struggling to find a bra that fits and has enough support and coverage, but I finally found it! Ended up purchasing 2 more in different colours.

Great

Hala A.

I recommend it's my second bra from this design

Small
