I'm taller at 5'7 and have a constant battle with bra straps.  With a 34B bra size I'm lucky to have a 1/2" of leeway on the straps. Convertible straps are out of the question, I barely have enough strap to go straight from front to back, definitely not enough to cross over.  This is a good comfortable bra, but my one complaint is the bra straps.  I've got them let out all the way and the straps are still a bit tight, you can see and feel them digging into my shoulders.  If this had another inch of straps I would be delighted with it.  Unfortunately it's a bit on the uncomfortable side due to the straps, but still more comfortable than a convertible bra and more secure than a strapless.  For me it's the best option out there, but still leaves a bit wanting.  I'd caution taller women that they might also find the strap length too short.  If you're taller than 5'7 I'd caution against it at all.  Outside of the straps, it is a nice bra.  So if you aren't on the taller side, go for it!  The cups are comfy, and it has lining over the underwire to help give it a seamless look.
