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.

The perfect bra!
Size: 46F, Color: Black
I love these bras because the back support is amazing allowing for perfect posture. I did need to size up the back as it didn’t have my cup size but is still incredibly comfortable. definitely a must buy!

Not for heavy or big busted women
Size: 42F, Color: Sargasso
I wanted to love this but there are issues. First: does it feel good around the back? YES! Second: it won’t fit well of you have a tummy or have a large chest. Reasons: the center closure turns sideways and doesn’t stay upright when on. Natural tension of being worn makes it pull and since it’s not sewn in tightly there, it moves and then you’ve got a wonky closure. If you have a tummy, this metal closure sticks into you every time you bend over. The points of the underwire-while nicely stitched in-are not padded and stick into you under the arm area and in front with every movement. A little better care when making could rid this issue. Over all fits to size, but you need to be thin and smaller chest size in order for this to work. Truly wanted to love this one.
