Always buy a t-shirt with a seam down the back - Why?
Do you like "bra-goo"?
What is bra-goo you ask?
That's the skin and flesh that gets trapped underneath your bra, causing it to create lumps and bumps on your back. It doesn't matter what size you are - bras give ALL of us bra-goo! That's just the nature of the bra - restrictive and binding. Some like to call it "bra-buldge", but I prefer bra-goo...it's funnier.
Since I don't love bra goo, I decided to do something about it. Every Dotty t-shirt, baeball tee, cardigan and sweatshirt tunic has a centre seam stright down the back. I designed them that way - to flatter our backs, smoothing out the lumps and bumps, instead of highlighting the "goo". This allows the fabric to drape away from the sides of the body, camoflauging the "goo" trapped underneath our bras.
So don't worry ladies - keep in mind, when you go to buy a top, make sure it has a seam down the centre back.
You will love the way your back looks.
