For back measurement: measure just under bustline (while wearing a non padded bra).
If measurement is below 33 add 5 inches. If above 33 inches add 3 inches. This is your band size. Band size is always even number so if yours is an odd number, scale up to next even number. For example if your measurement is 28 and you add 5 it reveals a band measurement of 33. Go up to next even number which is 34.
For cup measurement - measure fullest part of breast (again while wearing a non padded bra). Subtract the band size from this number. This number should range from 0 to 7 or even above. Tara Grinna accomodates up to an F cup which is a 7 inch difference. You should then have a band size and cup size. Combine these and this is your bra size!
At Tara Grinna, with some bra sizes, (102, 106, 112) we divide the band measurement into 2 figure types (smaller rib frame and larger rib frame).
If your band measurement is 32, 34, or 36 then buy 32/36 size top (this is basically a small rib caged or framed woman who will also generally wear a bottom on the smaller side of the size grid such as 6,8,10). If you have a 38, 40, or 42 band measurement then choose a 38/42 size top in these three styles. (Likewise this usually (NOT ALWAYS) means you are a larger framed person who will generally fit into a size 12 or up bottom).
If you are over a 42 or you prefer a looser feeling top, you will need to go up in band size or if you are already in the larger 38/42 band size you will need to purchase a matching fabric extender for the back ( look for extenders in accessories section of each print to accomodate this need). These extenders offer several back adjustments so that you can fit yourself comfortably.
Most other tops are available in exact band sizes of 32, 34, 36, 38, 40. Some tops are geared for smaller cup sizes and some are geared for larger cups. See description of each top for details. If there is no detail, then assume the top will fit a range of average cup sizes of B, C and sometimes D.
If there is a cup size option, then follow your band size and cup size measurement for your correct size. For example, the 104 top is available in 32,34,36,38 band sizes but also available in 3 cup ranges. AA thru A (AA/A), B thru C (B/C), and D thru DD (D/DD). If you are a 34B then you would buy a 34 B/C.
The remaining tops are available with Cup size only ( B , C, D, DD). This means that the band size is completely adjustable (most likely this top ties in the back so you can tie it as you prefer). We highly recommend that with any top like this that you tie the rib cage band as snugly as you can first, lean forward to place your cups into the top and then lift them up by securing the neck strap. This will give you the optimum fit and lift.
In all tops beginning with a B size option ( without an A cup size option ) please remember that in most cases the top will fit AA thru B size cups because of a removable pad inside the top).
*For all two piece tops we recommend that you secure the rib band first (the tighter the better for optimum lift and support), lean forward and lift breasts into the cups and then lastly secure straps either at neck or over the shoulder. If straps are over the shoulder, you should then pull back band down so that it rests straight on the back and not elevated above the cups. (stand sideways in a mirror and make sure your back strap is not riding above the bottom of the cups in the front).
