NEIWAI Expert Reviews

NEIWAI Review: Expert Reviews

NEIWAI is a very comfortable and interesting “one size” design, which stretches to accommodate and protect your body through weight swings, including pregnancy and postpartum! It is available in two strap styles: Classic and Spaghetti strap.

After wearing NEIWAI bras for a while, I can say that they are both comfortable to wear all day and even sleep in. You’ll definitely want one of each design — the Spaghetti is wonderful for wearing undershirts, but the Classic’s NEIWAI seamless comfort and broader strap support are unbeatable for wearing under anything else! Both NEIWAI collections have no clasps or closures and are meant to be worn over the head. While I don’t believe the “one size” will fit everyone perfectly, I’ve had friends ranging from a traditional 32A to 36D try this NEIWAI bra only find with positive feedback, but based on reader feedback, these may feel too big / bumpers too full for those with smaller busts or if you’re a 28 or 30 band size.

Full Review

NEIWAI becomes one of the top-rated comfortable bras from 15 options. According to the brand, NEIWAPI has a top-rated wireless bra that isn’t one-size-fits-all, but it can suit anybody with a cup size of 31.5-40 inches and an A-DD cup. It’s made of an ultra-elastic, moisture-wicking fabric that’s meant to keep lines at bay no matter what you’re wearing, and it has over 1,400 five-star evaluations from customers.

Full Review

I was recently introduced to the brand NEIWAI, which has designed a bra to suit you through all of your life’s sizes since “Your Size is The Size.” The bra is suitable for women with a band size of 30 – 40″ and a cup size of A – DD. Despite the fact that I am a 36DD, I felt that the classic design suited me better than the spaghetti strap because I am on the bigger side of the fit scale.

The traditional shape of NEIWAI includes a broad back and non-curling edge, and the spaghetti strap is removable, making it seamless and practically unnoticeable under clothes. Although the basic style fit well, I was pleased to know that NEIWAI also offers a “curve” model with a typical band size of 37.5′′ – 43.5″ and an A-DDD cup, which I think would be a better fit for me.

I found NEIWAI bra after I had finished breastfeeding and was postpartum. This bra is really comfy, and they provide me with enough covering and support. I’m a 36 or 38 B (size 8 or medium/large) and they fit well. If you need extra support, this may not be the bra for you. However, if you want a comfy undershirt that you forget you’re wearing, they are excellent.

This NEIWAI bras are wonderful, you guys! The fabric is to love, it’s perfect, flexible, and it’s wireless. It’s the ideal blend of soft and smooth, like butter! I’m also surprised by how supportive the fit is despite the lack of wire. I adore how these bras appear to adjust to my shape and fit like a second skin, regardless of how my body changes. They also look great beneath clothes, with no apparent lines!
