I'm not entirely sure if I measured the cups depth right. If I go from the decorative lace seam to the other side of the lace seam of the cup, across the apex line, it only measures 6", but if I measure actual space for your boobs, it measures 8", so I imputed a cup depth of 7". The straps are stretchy, I wasn't expecting that. The band is snug. The top of the front neckline, feels a little tight on my muscular and slightly full on top breasts. My left cup wrinkles because it's my smaller breast, so it shows a little through shirts. This fits just like my vintage bullet bra, but is a cup smaller, which is nicer fit for my smaller days. The appearance is a super conical/pointy shape.
This bra looks a bit grandmotherly, but it supports really well and promotes a classic feminine silhouette, but can be too 'pointy' for some. Given my shape, the gore doesn't tack, just hovers. This bra is not padded, so wearing tight, thin or flat color shirts may not be a good idea. The cups on this bra are full, so they have a minimizing effect and real harnessing abilities. If the bra is a cup size too small: they will produce mini-quad boobies--avoid these please and accept the larger size.
There is no under-wire, yet it holds it's shape well over time and through weekly machine washes, (air dry overnight). After 6 months of rigorous use, there isn't much deterioration of the bra's structure, but the color may change. If using harsh detergents, or drying in the dryer: the elastic woven into the wings may rubberize, become sticky and crumble.
Several of my bras of about 1.5 years are at this stage. The ones that maintain the lift and support I wear these to sleep or exercise.
