Love love love this bra.
Size: 34E, Color: Beige
I dont really write reviews but really felt like I needed to hop on here and give one. I have a terrible time finding bras that fit (small frame and my boobs never shrunk back down after having kids). I was initially looking for a non-underwire bra and ordred a couple to try. Was annoyed when this came in having underwire but thought ok, well its here so may as well try it. Fit like a dream so I told myself, Ill wear it for an hour and see how I feel about it then. I totally forgot I was wearing it. It is SO comfortable. The back doesnt ride up, I dont have underboob, it breathes nicely, holds me up, straps dont dig in or fall down, and I dont feel a huge sense of relief after taking it off at the end of the day. Ive ordered two more and after a few weeks of wearing and washing a couple times, I still absolutely love it.

The PERFECT bra!
Size: 38D, Color: Barely Buff
I typically don't write reviews...but I just had to with this bra! I have not worn an underwire bra in years. I have had such a hard time finding something that is comfortable, supportive and does not allow for overflow. This bra is perfect! The material is soft and stretchy. It covers everything and does it comfortably! It also provides a perfect lift! The color is a perfect skin tone. Pretty sure I will be buying more!

SUPER SOFT!! I'm impressed with how amazing this sheer bra feels on!!
Size: 46C, Color: Orchid Hush, Size: 46C, Color: Orchid Hush
I already loved Delimira front closure bras so thought I'd try these sheet mesh ones with Valentine's day coming up. Wow, was I super happy! The "mesh" that I have found scratchy on other brands was SUPER SOFT on this one. It's a stretchy fabric, but definitely is giving my C cups support. The size fit exactly as the other Delimira bras fit me. The shoulder straps feel wonderful too -- that's an added bonus. I was worried the back would be too much material and/or feel weird, but I loved how it felt and the coverage will make for zero tugging. This design is fantastic! As soon as I tried it on, I immediately ordered more colors and now have the light purple, red, white, and teal blue!! Oh and yes, it's sheer and will show your nips (some colors more than others), but not through a shirt. It provides the same coverage as other unlined bras under shirts. If you want a sexy bra that's comfortable too, this is it! My only complaint is that all the hardware on the bras are GOLD, no matter which color you order. I would prefer silver.

Comfy but don’t expect too much support
Size: 40F, Color: Snow White
Closure was a little stiff until I used it a few times. Fit was as expected; posture back feels good. Underwire isn’t uncomfortable at all. Mesh material is breathable and soft. Doesn’t provide real strong dupport so if that’s what you’re looking for you might be disappointed.

Delimira posture front closing bra
Size: 40DD, Color: Sargasso
This bra is great however there’s room to make it better. There is great back support & coverage of back fat as well as side fat. The strap is thick & comfortable. The strap stays in place also. The front closure is a plus however what does make it uncomfortable is the wire due to the length & the material needs to be thicker or maybe the wire should be some other material. The other part of it being uncomfortable is that the cups run oddly smaller & I sized up so if I go up another size the bra will be too big & not stay in place. This bra with some work could be excellent though.
