What Our Customers Say
Read reviews from women who found their perfect supportive D-cup fits.
"I struggled to find structured 30D balconette bras that didn't dig in. The Fantasie Illusion recommended by the size finder here is an absolute dream. Dispatched immediately by Uplifted!"
"I used the sister sizing tool to check whether a 32D or 30DD would suit me better in the Freya Deco. The detail on this website is fantastic and the 10% coupon DISC10 worked perfectly."
"I bought an Elomi Cate in 38D. It provides incredible support and side panels which shape so beautifully. Free delivery and dispatch was fast and efficient. Highly recommend this setup!"

How do I calculate a 42D bra size?
A 42D fits a ribcage of 42 inches. The bust measurement should be 46 inches, reflecting a 4-inch cup difference. Sizing is relative.
