Runs big size chart not accurate
Color: Black, Size: Small
I only put three stars because it runs large. Not a true small. I really wish they had xs. It's too big in neck and shoulders bunch up. The fabric is thick and not at all see through. I like the high neck and half sleeves. The fabric feels soft but also kinda "slick" so some people may not like that feel. For reference I'm barely 5ft and 115 and the small is too big. Not sure if I'm going to keep it or send it back. Price point it is a nice shirt

These Delimira bras are wonderful!
Size: 42DD, Color: White
I pray my five star review is worthy after having worn these two bras for a few weeks. I have to say the Delimira bras I have purchased lately are worth every penny as compared to more well known makers. They fit well. You can actually fasten the hooks and the bra remains comfortable. You girls know what I mean because the same size in Olga or Bali are made too small to even fasten them to put on. I hate it! These bras are wearable from day 1 and comfy too! Thank you Delimira!

Even an active old girl can feel secure and the girls will stay in place comfortably.
Size: 38D, Color: White
I am 135,5’6” and 78 yrs old. And size 38 D. The year I discovered my sports bras were discontinued I thought I was destined to bounce everywhere. Then I discovered minimizers. My ideal was a bra that stopped the bouncing in sports as well as the office. I could nap wearing it. Underwires were comfortable. My girls stayed in front. A wonderful shape evolved via this bra. Elegant with no unnecessary decor. Smooth under tshirts. What an elegant bra. May you have the same experience. Try it. adjust it at every option until it feels elegant,on you. Look and feel good in it knowing things will stay in place. Imagine that.
