Will be my go to strapless for sleeveless everything
Size: Medium, Color: Nude
Ok so, this did not disappoint. Supportive and has cups/padding so there's no show through. Stays in place. Sturdy will not roll on you or stretch out half way through your day/ evening. Straps are included but not necessary.
Do not try to put on right out of the shower. You also need to step into it to pull up. Do not try to pull it over your head.
Perfect for under spaghetti string tops/tube tops.
I am 135 lbs, 34DD or a 36D depends on bra. I bought a medium and it holds everything tight. I believe I could also go with a large at this weight to have a little less compression.

Very Comfortable!
Size: Large, Color: Nude
Very comfortable and supportive. I will use the clear straps because I had to take the pads out. They lend extra support but are a little too small. I wish they were as big as the cup. I couldn't go any larger or it would slide off. I am a 34DD and ordered the large. The clear straps are good, they don't feel cheap and they are easy to adjust. This is the most comfortable strapless bra/clear strap bra I've ever tried.

Really great quality and fit for the price
Color: Navy Blue, Size: Large
These tank tops are beautifully cut, the colors are great, the fabric is stretchy and comfortable and they don’t look at all cheap. A very welcome surprise that they exceeded expectations. I spend the entire summer in slim fit tanks and A-line skirts with a jean jacket or shirt over and ended up buying practically every color because I like them so much - can pair them with much more high end items and they don’t look out of place.

Super soft, nice material and you'll want a few of these!
Color: Black, Size: Medium
I’ve been really happy with this ANRABESS ribbed V-neck tank overall. It fits snug, and the material is soft, stretchy, and lightweight, which makes it perfect for warmer weather or layering it.
The ribbed texture and V-neck give it a slightly more polished look than a basic tank, so it’s easy to dress up or keep casual with jeans or shorts. I’ve found it to be comfortable for all-day wear, and it holds its shape well after washing. I really like the wider shoulder material which covers my bra strap well.
Fit-wise, it runs pretty true to size, although I could see sizing up if someone prefers a less fitted look. One thing to note is that lighter colors may be a bit more sheer depending on what you wear underneath.
Overall, it’s a simple, versatile tank that didn't break my bank so it's worth it. In the winter I'll probably wear it under the majority of my shirts. I'm absolutely planning on ordering more colors.

Perfect flattering tank
Color: Hot Pink, Size: Large
These are the best tank tops! No gaping arm holes. The tank gives some coverage on the sides and under the arms so it conceals any problem spots. The back neckline is higher than most tanks so the straps are a perfect flattering length for me. I'm under 5'3 with a short torso so it's rare to find a tank that doesn't require shortening the straps. The V-neck is wide and hits at the perfect spot, not too high to be awkward looking but not so low that I'm flashing people at dinner. The fabric is light- medium weight. Not so sheer that it looks cheap but not thick enough for the white to be opaque. These are well made and hold their shape after washing and drying and come in a ton of colors. I have several and will buy more.
