Comfortable Fit without over compression
Size: 38B, Color: Gentle Rose
This is a good post surgical bra. I had a lumpectomy and it gave me enough support without being too tight. It is adjustable in the front and the shoulders. Use the size chart to get your best fit. Soft material. Comfortable enough I wore it 24/7 for a couple days. Only downside is handwashing but I will try the delicate cycle on my machine and air dry always.

Awesome bra!
This bra is so comfortable. I love the fact that you can adjust the straps and the front to make it fit a short person's torso. This bra lifts and so far, has not stretched out.

Soft and Comfortable
Size: 46D, Color: Black
Size 46 D, black. Very Comfortable ! The strap adjustments are in front so it would be easy for someone who needed a caregiver to help them dress. The cups fit well with no gaps or wrinkles and the back lays smoothly, with no irritating seems or crossovers. The chest band is one piece, so no irritating seams, and its a little more supportive than my usual at home or bedtime bras. I tried it on and decided to wear it an hour to see if it stayed comfy while I moved around the house. It was so comfortable I forgot to change it! I ordered the black and when I machine washed it there was no dye bleeding. Hung to dry. Wearing it again and I think it just might become my new favorite. If I still love it, I might purchase another color in next month's shopping budget.

Extremely Comfortable
This bra is the most comfortable bra I have worn. It is so comfortable it doesn't even feel like I am wearing a bra. There are no unfinished seams inside. I like the fact the shoulder straps are hook and eyes that don't slip like the conventional straps. This bra is reasonably priced and nicely made with good support.

DELMIRA BRAS
Size: 36DD, Color: Gentle Rose
I don’t care for this bra whatsoever. The material is very cheap, has no support and in a nutshell, it’s one of those bras you can wear to bed if you’re not feeling comfortable going to bed braless. The price ($19.99) is very high for this bra. It’s definitely not made well or worth the price. I’ll never buy from Delmira again.
