Where is OP located? If in So Cal..LA or Orange County...she might want to check out The Unlikely Cyclist in Costa Mesa. It is a women's cycling shop/boutique that carries several lines of cycling clothing for women of all sizes and shapes

she can find the store and ask questions of Lisa (Vntgdrms) on Facebook too

honestly...even if NOT in the area I recommend OP getting in touch with Lisa as she is fantastic about finding clothing to fit someone even w/o meeting them in person...just ask PhotoJoe who bought his wife some stuff and Lisa used his description to pick stuff out and from what I heard she loved the stuff.
