Hi Julie....firstly welcome to this wonderful world of support and love (sorry u had to tho)..now, shopping- My advice is button up PJ tops or oversized shirts (still button up front) and as for bras- then u can get front opening soft bras ( i got some thru the local hospital - they had a person who would fit u for mastectomy bras) maybe check with them or ur breast care nurse where u can source these from locally...U should also get "MY Journey Kit" & "My Care Kit" from the BCNA, again check with ur Breast Care nurse as she orders the Care KIt for you-it will have a soft form prosthesis and a bra included. Don't be in too much of a hurry to wear anything other than a shirt (at least for the 1st week or so) u may have drainage tubes and bandages covering wounds-the less 'extra' clothing the better--just as long as ur comfy, thats the most important thing :)
Now, onto other business :) Please feel free to come here as often as u wish as u navigate ur way around this detour life has thrown u- u may feel a whole range of emotions and feeling (many in the same day!!!) and everyone here truly knows what ur going thru and can (& will) offer a sincere shoulder, helpful advice and first hand understanding...
Have fun shopping, good luck for ur surgery, keep us posted
Sam :)
