Navy Broderie Sleeve T-Shirt

The cut of the sleeveless hole by the armpit is so big you need to wear another top under it which is pointless. To rectify this need it tailored withsome material to cover although this makes it look even bigger. I could not return as was unwell and love the broderie design personally I think it was a waste of money and a headache to rectify now. This I the second time I have noticed the really poor quality in sizing and stitching and numerous reviews show this but seem to be ignored. I have to get someone else to return items for me. So always buy the right size or or larger 90% of the time but this was ridiculous fit everywhere but the actual armpits being to big that half the side of my body was showing and not in a nice way! Matalan sort the sizing out please!
