Fräulein Annie is an independent lingerie and swimwear brand, founded 2010 in London by German-born designer Frauke Nagel. It's now based in Germany, and uses vintage influences to create classic lingerie in A-G cups, sizes UK 8-18. Deliciously unusual colour palettes and fine details feature heavily.
All the garments have stretch fabrics so there is some flexibility of fit. The bras use the old fashioned plus 4 method and the bands are tighter than modern value brands.
To find your bra sizes, measure your underbust, add 3-4 inches to bring it up to an even number. This is the back size (30,32,34,36 or 38). Then measure your overbust. If there is no different to the back size, an A cup should work. For a one inch difference, a B cup, 2 inches, a C cup, 3 inches, a D cup, and 4 inches a DD cup.
For S/M/L sized garments, Fraulein Annie recommend that they are roughly equivalent to:
Small - UK 8-10, EU 36-38, USA 4-6
Medium - UK 12-14, EU 40-42, USA 8-10
Large - UK 16-18, EU 44-46, USA 12-14
