The Oh My Girl hoodie you're looking at is a good quality piece of apparel featuring the logo of the girl group on front. It of course present itself the best on a black background, but is available in other colors.
The hoodie was made of a fleece composed of cotton (80%) and polyester (20%). The fabric was manufactured following the rules of WRAPS (World Responsible Apparel Practices Standards) and is very soft. The Oh My Girl hoodie will be very comfortable to wear and easy to wash. You can wear it casually inside and outside the house. It has a drawstrings, a big pouch pocket on front and ribbed cuffs.
As I mentioned before the white logo of Oh My Girl will look better on a darker background, but there are 6 different colors to choose from including black, oatmeal, heather grey, charcoal heather, blue and dark blue. You can get the one that matches your taste the most. The variety of colors you can choose from is rather large.
The hoodie comes in 5 sizes ranging from S to 2XL. There will be no problem with getting the right one for you. The measurements are: S (chest: 40 inch, length: 27 inch), M (chest: 44 inch, length: 28 inch), L (chest: 48 inch, length: 29 inch), XL (chest: 52 inch, length: 30 inch) or 2XL (chest: 56 inch, length: 31 inch). These are not the Asian sizes so you can be sure you will be getting what you expect. If you prefer your hoodies baggy you should consider ordering two sizes up.
You can get this Oh My Girl hoodie from Redbubble, either with the print located on front or on the back. The price is very reasonable considering there is not many these kind of items related to Oh My Girl on the internet.
