Ex Input:
I purchased this item in D and the cups were much too small. So then I purchased again in DD. They still did not work well and I decided to go with traditional shapewear for better support. Turns out, neither of these two items I purchased are available for return and I cannot use them. What a complete waste of money!

Great quality. Hooked right up to my monitors and stand. No complication whatsoever. The fit is a little tight, but you want that with $200+ monitors.
