LOVE this brand
Size: Medium, Color: White Blue Florals
Okay I am really falling in love with this brand I have a couple of shirts and dresses and pants and I absolutely adore all of them. The material all of it is so much better, such top quality and extremely soft and wonderful feeling up against your skin more so than you would ever think. The size is perfect I ordered a medium and I normally wear a medium, it is perfect for playing golf or tennis, it is breathable so as I run the wind cools me off. I like the way that the shirt looks and it stretches a bit so you can you know get it on but it does not lose its shape or anything like that. It washes and dries very well it keeps its shape and does not shrink and honestly in my opinion it it feels like it gets softer the more you wash it the more you wear it I don't know

Pretty in pink!
Size: Small, Color: Pink White Florals
I ordered this top in the pink color, and it is absolutely lovely! The print is feminine and cheerful, making it perfect for golf, tennis, or any casual summer outing. The fabric is soft, lightweight, and breathable, which is a must for warm weather. It does a great job keeping you comfortable, even on hot days, and the sleeveless design allows for easy movement. My only note is that the fit runs a bit snug. If you’re between sizes or prefer a looser fit, you may want to consider sizing up. Other than that, it’s a very well-made top with a flattering style and beautiful color. Overall, a pretty and comfortable addition to any warm-weather wardrobe! 💗⛳🎾☀️

Lightweight, Great Quality, Fit Might not be Perfect.
Size: Medium, Color: Blue Plaid, Size: Medium, Color: Blue Plaid
Cute, comfortable and breathes like a spring breeze! The only complaint here is the fit. Several folks mentioned it not being a loose fit, we had the opposite problem, fit the chest and shoulders perfectly, but a bit baggy in the mid section. Tucked in, it kind of muffin tops out a bit, but loose it is lovely how much this thing breathes. Overall I think we are going to try a size down, but will update once we have a better handle on that. Quality wise, this shirt is great, strong, lightweight material that I can see lasting as long any other brand.

The stretchy feminine fit, very comfortable and great value
Size: Small, Color: Lavender Rose
I review promotional products and only give my honest opinion, others may have a different opinion. LOVE this golf shirt! The material is a really nice quality, so soft and a stretchy fabric. The print and color is really nice too! The lavender/lilac is so pretty. Rarely can I find this color in this type of top. I love that it’s sleeveless with the high collar. And it’s not a cropped fit, it sit at my lower waist. I’m 5’3” 120-125lbs’ish and 34DD and the size small fit me PERFECT! Very flattering fit. Comes in at waist and flares a bit at the bottom seam. This golf shirt by M MAELREG is versatile through the three seasons. A lightweight yet thicker material. Sweat absorbing. Def give this golf shirt a “YAY!”

Golf-Shirt or not; My daughter's most Favorite
Size: Medium, Color: Black Gray Blocks
Whether this is a Golf-Shirt or not, it's my daughter's most Favorite dress now after I gave her, last week. She now wears it at her office, at parties, and even at home when playing with her son. So, in that sense, you don't have to buy costly golf equipment and get another costly membership - just dress up with it and go anywhere and get admired. Its low neck design with a short zipper in front and sleeveless sides makes it most modern-looking. This shirt is nice and very lightweight, having a base material of polyester added with spandex. This also makes it moisture-wicking and breathable. The fabric has a coolness to it that would make an appropriate dress for the coming summer.
