How To Measure

Follow these steps for your perfect fit

1. Get a measuring tape

You can do this on your own or get a friend to help. Wear a non-padded, wired bra for best results. Always relax and make sure your arms are by your side.

2. Find your band size

Align the tape around your body at ribcage level, directly under the bust, keeping the tape parallel to the floor. Tape should feel snug but not tight around the body. Record your measurement.

Find your band size according to the measure chart.

Measurement/Band Size

27-28"	29-30"	31-32"	33-35"	36-38"	39-41"	42-44"
32	34	36	38	40	42	44

Measurement	Band Size
27-28"	32
29-30"	34
31-32"	36
33-35"	38
36-38"	40
39-41"	42
42-44"	44

3. Find your cup size

Wrap the measuring tape around your body at the fullest part of your bust, ensuring the tape is parallel to the floor. The tape should fit comfortably around your body. Take note of this measurement.

Then, subtract your band size from your bust size to determine your cup size.

* For instance, if your bust measures 36 inches and your band size is 32 inches, the difference is 4 inches, indicating a cup size of D.

Reviews Summary

Customers say this bralette is incredibly comfortable and lightweight, perfect for warm weather. The mesh material feels soft and breathable, with many noting it's so comfortable they forget they're wearing it. The sheer design is beautiful and flattering while still providing moderate support without underwire or padding. Common feedback includes praise for the fit and stylish appearance, though some mention needing to size down. Many customers have purchased multiple colors. A few note the band runs large or straps may slip on smaller frames, and one customer mentioned the velvet flocking design affected cup fit. Overall, reviewers love the balance of comfort, style, and support.

Perfection
This bralette is perfection. I purchased it in four colors. It is very comfortable but still gives good support. They give a beautiful pop of color under sheer tops. Additionally, the design is gorgeous.

Happiest I've been with a bra in years
This bra actually is as advertised. Lightweight but somehow supportive. Extremely comfortable, in fact, it feels like wearing nothing. Not a single red mark anywhere for as closely as it fits. With no padding it's cool and easy to wear. It's such a relief to have a bra brand that I can rely on.

I Have Been Searching For Years!
As a 40+ woman, bra comfort is a top priority. I have been searching for a comfy wireless bralette for years. Some of the ones I have bought were okay. Good, even. But after I tried this one on, I saw how wrong I was. Those bras were all inferior! This bra is a 10/10. THE MOST COMFORTABLE BRA EVER! I am 36D, and I am so happy I finally found my match.
